Best Java Libraries for XML Data Processing




Users continue to rely on XML (eXtensible Markup Language) for data exchange and storage across Java applications because it delivers adaptable structures for complex information representation. XML demonstrates wide industry application because of its platform-independent format that produces human-readable content. 


However, the processing of XML data requires careful management due to its difficulties including efficient parsing of big files and database storage consistency with data integrity and fast data transformation.

Top Java Libraries for XML Processing



The selection of a library depends on two factors: the level of task complexity and the set criteria for system performance.

Java thread synchronization

Do you know what is thread synchronization Java? Have you ever thought about how to use synchronized in Java? let us gain some knowledge about thread synchronization Java & try to find out the answer to what is thread synchronization in Java.

But before we start writing about thread synchronization Java & try to find out how to use synchronized in Java. Let us first try to understand the policy of synchronization from one daily life example.

Assume one daily life scenario.

Suppose in your school, there is one toilet for the gents. Now, at the same time, you & your friend need to access the toilet. In both cases, the matter is an urgent one. So, you are not ready to let him go. Neither of your friends is ready to let you go. As a result, there is a mess in front of the toilet.

So, what you will do in such a case? Or what your friend will do at that time?

So, you called the teacher to solve the situation that arise there. Your teacher will draw a solution & allow anyone to go to the toilet first. And as a teacher is a respected person both of you are ready with the solution. In this case, the teacher helps to solve the conflict.

The same thing happens in thread synchronization Java. When two different parts of the program try to access the same resources then this trouble arises. We will try to know more about it when we discuss what is thread synchronization in Java.

What Is Thread Synchronization in Java:

Java is an important programming language. Java is used in the corporate world as it helps to solve real-life problems very easily. Java is used for game development purposes. These along with an operation some more processes are going on. For implementing that situation, Java programming language used the thread concept. Thread is a special concept of the Java programming language. It helps to execute more operations a t same time.

Synchronization means collaborating two or more processes at the same time. The thread synchronization Java is quite like this. Now, sometimes when two or more processes are using the same resource then there will be a problem. This problem arises when we use thread in Java. Two or more parts of the code want to use the same resources. Then there is a mess at that point.

The main goal of thread synchronization in Java is to remove the problems related to resources. If two or more parts want to use the same resource, then one by one they will execute that. This means one part will use that resource, then it will be removed. After that, another part is going to use the resource & will be removed. This is a very problematic situation. To come out of this situation, we used the 'synchronized' keyword.

Synchronize is like the teacher at your school. It helps to remove the conflicts between two or more parts for using the same recourses. We will find out more about this when we implement the thread synchronized Java. Similarly, when you are stuck at Java coding you can use Java Assignment Help Services from codingzap.

Why Should We Use Thread Synchronization Java:

Now, after knowing about thread synchronization Java, we need to know why we should use it. This is a very important topic. Often, we find out that, the threads that are implemented in the program are not executing the same we want. In those cases, we need to use this method. As there is a problem related to the synchronization.

If we don't use synchronization, then there will be an issue related to the memory space. Also, the flow of the output of the program will not be similar as desired. There will be a thread interface problem if we don't use synchronization at the correct time. When we implement thread synchronization Java, it will be easy to understand.

Why Higher Learning Institution Prefer to Teach Java Than Python


Python and Java are two of the most widely used programming languages. Due to its computability, Java is typically more efficient than Python. Python's syntax is simpler and more succinct than Java's since it is interpreted. Using less code than Java, it can do the same thing. However, large number of students, programmers, professors in most reputable universities spend much time training java.

Much of Java's efficiency is due to its Just-In-Time (JIT) compiler and its ability to handle concurrency. The JIT compiler is a component of the Java Runtime Environment. Compiling byte-codes into native machine code "just in time" to execute Java applications enhances their performance. The Java Virtual Machine (JVM) directly calls the built code. Compiling does not use a lot of resources since the code does not have to be parsed. This could theoretically make a Java program as quick as a native application.

Another reason making java most popular among students looking for programmingassignment help online is due to its user friendliness especially when doing the coding part. Bugs, errors, and all other issues affecting the code are clearly indicated in the runtime, not like in python. Programmer errors in Python are not discovered until the code is executed. This might lead to operational failures and a longer turnaround time, which is not ideal. Object mutation is impossible in Java, although it is feasible in Python. This leads to the creation of secure software. Fixing bugs is an hectic task, that may make programmers and students look for programming help online and bestwebsites offering programming assignment help.

Python may be more flexible and user-friendly than Java, but Java is still the best "formal" language out there. It is statically typed, has all of the OO implementation bells and whistles, and tends to function in a manner that rewards proper program design. That makes it a great choice for teaching at the college and university levels. Computer Science students find it difficult to spend much time in the laptop while avoiding some best moments as a college student. However, with good programmingassignment service, such as ThePandaPapers, students may now get professional help with all sort of programming tasks, may it be java, sql, or python. They have programming assignment experts

StackOverFlowError: Causes & Solutions


StackOverFlowError is one of the common confronted JVM error. In this blog post lets learn inner mechanics of thread stacks, reasons that can trigger StackOverFlowError and potential solutions to address this error.

To gain deeper understanding in to StackOverFlowError, let's review this simple program:

<<start:code>>
public class SimpleExample {

      public static void main(String args[]) {
           
            a();
      }    

      public static void a() {

            int x = 0;
            b();
      }

      public static void b() {

            Car y = new Car();           
            c();
      }

      public static void c() {

            float z = 0f;
            System.out.println("Hello");
      }
}
<<end:code>>

This program is very simple with following execution code:

1.       main() method is invoked first
2.       main() method invokes a() method. Inside a() method integer variable ‘x’ is initialized to value 0.
3.       a() method in turn invokes b() method. Inside b() method Car object is constructed and assigned to variable ‘y’.
4.       b() method in turn invokes c() method. Inside c() method float variable ‘z’ is initialized to value 0.

Now let’s review what happens behind the scenes when above simple program is executed. Each thread in the application has its own stack. Each stack has multiple stack frames. Thread adds the methods it’s executing, primitive data types, object pointers, return values to its stack frame in the sequence order in which they are executed.

Benefits of call stack tree




Call Stack Tree provides 3 wonderful benefits:
  1. One simplified view
  2. Performance Optimization
  3. Accurate Smoke Test

Let’s discuss them in detail in this article.

1. One simplified view

Thread dumps are the snapshot of all threads running in the application at given moment. Thread dump will have hundreds/thousands of application threads. It would be hard to scroll through every single line of the stack trace in every single thread. Call Stack Tree consolidates all the threads stack trace into one single tree and gives you one single view. It makes the thread dumps navigation much simpler and easier. Below is the sample call stack tree generated by fastThread.io.


                                            Fig 1: Call stack Tree

You can keep drilling down to see code execution path. Fig 2 shows the drilled down version of a particular branch in the Call Stack Tree diagram.


                                            Fig 2: Drilled down Call Stack Tree

Call Stack Tree shows you the class name, method name, and line of the code that has been executed and the number of threads that have executed the line of code.

                                     Fig 3: A single element from Call Stack Tree

From the above element in the Call Stack Tree, you can identify that call() method in buggyCompanyCallable.java is executed by 9 threads.

What is new with Java 9

Being a Java professional, if you were waiting for the big news then finally here it is - Java 9 has been released into the technical workspace recently and the features embedment is just amazing. In this article, we will take a quick tour of the new features introduced in Java 9 and how they can help you in getting your programming skills better.

The modularization with project Jigsaw

After the release of Java 8, Lambdas and improved APIs functionalities changed the daily life of the Java developers. However, one feature that was awaited since a long time to become the highlight of freshly released Java 9 version i.e. modularization with the project jigsaw.

Before modularization, JDK was defined as a programming environment with various undesirable dependencies between different areas of implementation. There was a quick need to eliminate all of these dependencies to get a more modular Java program.

The Jigsaw module system helped in starting compilation with base module only. The Java applications can be started by installing base modules only that are actually needed by the program, not any other undesirable module components. In this way, it will enhance overall runtime and compile-time capabilities with the reliable configuration setting enhanced encapsulation mechanism.

With Java 9, you would be able to design your own modules with the declaration of multiple packages inside. Let us see a quick example, how to create or define modules in Java 9 version.



In this example, we have been used two keywords “exports” and “requires” with significantly different purposes. The “Exports” keyword will tell you about the packages you wanted to show to the outside world. At the same time, the “requires” keyword signifies about the packages you need from the outside. The concept may be a little bit confusing at first glance, but it goes really interesting with practical implementation.

Modules can also be used as classical JAR files inside classpath. In Java 9, modularization concept has replaced the keyword “classpath” with “modulepath” where you can find all the modules declared by you.

Domain-driven design with Java 9

With the introduction of modularization in Java 9, it has become possible for the developers to make software architecture better and more expressive. Now the layers in software architecture can be defined as modules and each of the interfaces can be defined more precisely as compared to the past.

This would be easy for the compiler as well to detect or prevent the architecture violations. Let us have a quick look on domain-driven design with Java 9 –

What is Garbage Collection log? How to enable & analyze?


Objects are created in the memory to service incoming requests. Once requests are serviced, newly created objects will become useless (i.e. garbage). This garbage must be evicted from the memory so that there is enough room created in the memory to service the new incoming requests. If there isn’t sufficient memory, the application can experience poor response times, OutOfMemoryError, and fatal crashes.
In Java, Android, C#…, garbage collection is automatic, whereas in the several predecessor programming languages (C, C++) – programmer must write code explicitly to release the objects after they are used. So, it’s a major convenience for Java, Android, and C# application developers. But this automatic garbage collection is not free, it comes with a price. Automatic Garbage Collection can have a profound impact on:
1.       Application Response Time
2.       CPU
3.       Memory

Application Response Time

To garbage collect objects automatically, entire application has to be paused intermittently to mark the objects that are in use and sweep away the objects that are not used. During this pause period, all customer transactions which are in motion in the application will be stalled (i.e. frozen). Depending on the type of GC algorithm and memory settings that you configure, pause times can run from few milliseconds to few seconds to few minutes. Thus, Garbage Collection can affect your application SLA (Service Level Agreement) significantly.

CPU

Garbage collection consumes a lot of CPU cycles. Each application will have thousands/millions of objects sitting in memory. Each object in memory should be investigated periodically to see whether they are in use? If it’s in use, who is referencing it? Whether those references are still active? If they are not in use, they should be evicted from memory. All these investigations and computation requires a considerable amount of CPU power.

Memory

Of course, poor GC configuration can lead to high memory consumption and vice versa. Most applications saturate memory first before saturating other resources (CPU, network bandwidth, storage). Most applications upgrade their EC2 instance size to get additional memory rather to get additional CPU or network bandwidth.
Thus to have top notch SLAs and reduce the bill from your cloud hosting provider, your applications Garbage collection has to be function effectively.
In order to study and optimize Garbage Collections impact on the application’s performance, one has to enable Garbage Collection Logging. Besides that, Garbage Collections logs can be used to troubleshoot memory-related problems in the application.

Poor Employers in the Age of Technology

http://www.vantigeinc.com/hs-fs/hub/168341/file-238178968-jpg/bigstock-Helpless-young-business-woman--42586567.jpg?t=1492713388190&width=1349&name=bigstock-Helpless-young-business-woman--42586567.jpg



Every entrepreneur desires to have most skilled, diligent, well-mannered and reliable professionals. This is probably because the employees are the strength of an organization having the power to make or break it. While the motivated, creative and problem-solving employees support employer to flourish the business, the lazy, fickle and unproductive workforce can cause huge loss to the company.

Mostly it is a poor recruitment process that let the losers enter into the organization but sometimes the blame of turning a skillful person into unproductive creature goes to the technology. While the technological advancement has changed the human lifestyle, it has also changed the environment of workplaces. It is hard to imagine an office without computers, the internet, air conditioners and supportive technologies. While all these pieces of machinery have become necessities to work, these are the hindrances as well. So, the chances of employer bearing huge monetary loss or, in worst cases, losing his business are more because of the facilities provided to the employees than just the lack of efforts.

We have rounded up here a few basic facilities provided by the employer to its workforce that reversely cause his own failure.         

Internet – The main distraction that kills productivity

While the internet is a compulsion for online businesses, software houses, and many other businesses, it is full of distraction. Smartphones, social media, and emails are among the major workplace productivity killers. While the employer provides its employee with the internet for work-related tasks, the mischievous guys use the service for updating their Facebook profiles, playing games, and watching YouTube videos. Resultantly, they fail to accomplish their tasks at the time and make the employer bear the loss.

Have you ever wish to learn about AngularJS framework for java web development?

Though online article directories and blogs of Java web development professionals are feed with distinct stories and articles about different products; still you can consider this post to learn every important fact about AngularJS. The author will explain the framework, its features, architecture, and the steps to build an AngularJS application. Read every point thoroughly to get a clear vision about the framework.

AngularJS is an open source javascript framework for web application. It was originally developed in 2009 by Misko Hevery and Adam Abrons. It can be added to an HTML page with a <script> tag.

Definition of AngularJS:

AngularJS is a structural dynamic web apps framework. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. Angular's data compulsory and dependency injection eliminate much of the code you generally have to write. And it all occurs within the browser, making it an excellent partner with any server technology.

Features of AngularJs:
  • AngularJS is a powerful JavaScript based web development framework which is useful to develop powerful web application.
  • AngularJS provides developers options to write client side application in a clean MVC architecture.
  • Application written in AngularJS is cross-browser compliant. AngularJS automatically handles JavaScript code for each browser.
  • AngularJS is open source, completely free, and used by thousands of developers around the world.

Overall, AngularJS is a framework to build large scale and high performance web application while keeping them as easy-to-maintain.

AngularJs is divided in three major parts which are called ng-directives. Those are listed below.
  1. ng-app - This directive defines and links an AngularJS application to HTML.
  2. ng-model - This directive binds the values of AngularJS application data to HTML input controls.
  3. ng-bind - This directive binds the AngularJS Application data to HTML tags.

Top Ten Reasons for learning Java Programming Language

Java is the best programming languages created ever as it has last 20 years by gaining popularity every passing day. Although there were occasions when Java development slowed down, but with path breaking changes in form of Enum, Autoboxing and Generics in Java 5, Google's choice of language for Android apps development and performance improvement with Java 6, kept Java as top programming language. Also In terms of Job opportunities and popularity Java outscore every one with lots of Jobs opportunity available. You can work on developing core Java based server side application, can even go for Android based mobile application development and J2EE web and enterprise applications.

Here are top 10 reason for Learning Java Programming Language

1) Java is Easy to learn

Java has fluent English like syntax which makes it easy to read Java program and learn quickly. Once you are familiar with initial hurdles with installing JDK and setting up PATH and understand How Classpath works, it's easy to write program in Java.

2) Java is an Object Oriented Programming Language

Java is an Object Oriented Programming language. Developing OOPS application is easier, and it also helps to keep system modular, flexible and extensible. You can use all key concepts like AbstractionEncapsulationPolymorphism and Inheritance. Java also promotes use of SOLID and Object oriented design principles in form of open source projects like spring, which make sure your object dependency is well managed by using dependency Injection principle.

3) Java has Rich API

Java provides API for networking, I/O, utilities, xml parsing, database connection, and almost everything. Whatever left is covered by open source libraries like Apache Commons, Google Guava and others.

4) Powerful development tools e.g. Eclipse, Netbeans

Eclipse and Netbeans has played huge role to make Java one of the best programming language. Coding in IDE is a treat, especially if you have coded in DOS Editor or Notepad. They not only help in code completion but also provide powerful debugging capability, which is essential for development and testing. Integrated Development Environment made Java development much easier, faster and fluent. Apart from IDE, Java platform also has several other tools like Maven and ANT for building Java applications, JConsole, decompilers, Visual VM for monitoring Heap usage etc.

5) Good collection of Open Source libraries

Open source libraries ensures that Java should be used everywhere. Apache, Google, and other organization has contributed lot of great libraries, which makes Java development easy, faster and cost effective. There are framework like Spring, Struts, Maven, which ensures that Java development follows best practices of software craftsmanship, promotes use of design patterns and assisted Java developers to get there job done.

Five Common Questions from JavaScript Beginners

What is JavaScript?


JavaScript is an easy-to-use version of programming language (a constructed language that communicates instructions to a computer).  JavaScript is a scripting language (this means it is a programming language that supports scripts, which can interpret and automate the execution of tasks). Developed by Brendan Eich, while working for Netscape Communications Corporation, this program code was designed to appeal to nonprofessional programmers.  JavaScript runs inside an Internet browser. JavaScript is not a stand-alone programming language.  JavaScript is designed to embed information  in a web browser.  JavaScript includes the following features: dynamic typing and has first-class functions.  

Is Java the same as JavaScript?

Though both Java and JavaScript are both programming languages they are also immensely different.  Java is a very complex programming language while JavaScript is an easy-to-use version that is great for those beginners learning about program languages.  JavaScript and Java have the same expression syntax, naming conventions, and basic control-flow constructs.  JavaScript was previously named LiveScript; the name change has caused much confusion between Java and JavaScript.  Java is a programming language that can be used as a ‘stand-alone’ whereas JavaScript must rely on the environment it is operating in.


How Does JavaScript Work?

JavaScript works by placing code within a Web page.  When a browser loads the page, the built in interpreter reads the JavaScript code it finds within the page and runs it.


What is JavaScript Used For?

JavaScript is mostly used to allow ‘client-side’ scripts to interact with the user.  It is also used to control a Web browser, alter content that is displayed in a document, game development, as well as desktop and mobile applications.  Real life applications where this can be used (outside of web pages) include PDF documents, site-specific browsers, and desktop widgets.


What are the Various Data types used in JavaScript?

Number: Numbers can be written with or without decimals and may use scientific (exponential) notation if they are large enough. Does not allow the use of non-numbers such as NaN.

String: Strings are written with quotes.  Either double or single. 
Boolean: Can only have two values: true or false.
Array: Arrays use square brackets ‘[]’ while separating elements with comas.
Object: Objects are written with curly brackets ‘{}’. Comas separate each pair while the colon ‘:’ separates the name from its value.
Null: An empty value.  Variables can be emptied by setting the value to null.
Undefined: The value of a variable with no value.

Handling Suspicious Email Messages

There has been significant increase in the circulation of spam and malicious emails in the recent past. In this article we will discuss how to handel suspicious email messages. It is very important for you to identify the spam and take steps to safeguard yourself against potential threats.


How to identify spam without opening the message?

A malicious email can infect your system immediately. Downloading a file from a suspicious email is enough to infect your system, including a PDF. Do not open suspicious or unsolicited emails.

It is recommended :


  • Do not open suspicious emails
  • Try to identify a message as spam by looking at the 'From' field and the 'Subject' line. If the sender and the domain (@company.com) does not relate to the subject, the message is probably spam
  • Never trust emails that are trying to sell you something or unknown clients. Ask yourself, does the sender identify you by your name? If the answer is no, the message is spam. 


You can identify spam emails by looking at the 'From' field, if :


  • You get any email with your name in as the sender (which you may not have sent) 
  • The 'From' field is blank or generic (example: friend, try this, etc.)
  • The mail has strange name or all numbers – 9222594_1970@tst-inc.com 
  • Has scrambled, random-appearing addresses – X12YT853@yahoo.com 
  • Is from someone you do not recognize or from a domains like yahoo.com, gmail.com, msn.com, hotmail.com. Attackers use these domains to send spam 
  • If the message is from another country, especially, if you do not work regularly with them (Example - m5wangzhi@wahaha.com.cn – here CN means the domain is China) 


You can identify spam emails by looking at the 'Subject' field, if :


  • The subject is unrelated to your work profile or domain (example: Do you want to get rich?) 
  • There are strange characters in the subject (example: best m0rtgage qu0te!s") 
  • There are obvious spelling errors (Example: buy yourself Bacheelor/MasteerMBA/Doctoraate dip1omas)
  • The subject is outrageous or doesn't make any sense (Example: BREAKING NEWS: Nuts! Jackson Backs Neutering Stray Politicians)
  • The subject appears to be an order of confirmation for something you did not order (Example: Your Tracking # 77328515")
  • Your email address is in the subject line, this is usually done to gain your interest to open the email
  • The subject line indicates an important notification ("Install update for Microsoft Outlook"), and the message appears to be from the vendor (for example, Microsoft). Remember, Patches can be installed by clicking on Start -> Control Panel -> Windows Update

Top 5 Popular jQuery Plugins


Author Bio: Danica loves technology and she constantly advises people on the best web hosting platforms for using jQuery as well as a host of other coding libraries. She is an expert at using PHP and hopes to start her own development company in the future.

jQuery is one of the most popular libraries available to webmasters and developers, and a big reason for that is the large number of high quality plugins that are available. These help novice webmasters and developers to create professional looking websites filled with different features, while those with experience can use jQuery to add the finishing touches to what is already an exceptional platform.

That said, one of the worst things for a developer to do online is to overuse plugins, widgets, and various other things that are available in order to enhance the user experience of a website. With that in mind, we have looked at five of the best and most popular jQuery plugins you could use on your website.

Cycle 2

If static images are a big part of your website, then the Cycle 2 jQuery plugin is a great way to take your imagery to the next level and create exciting slideshows on your web pages. What makes this plugin a winner is that it is so easy to use; all you need to do is include the plugin and mark-up to your code, and everything else is done for you. Although this is the perfect plugin for new webmasters or bloggers, it is also loved by those with great knowledge of web development owing to its ability to work within responsive design themes.

FitVids

While many people fret about how having video content on their website will slow down loading times, some struggle to even get video onto their pages at all. Those who want to make video a feature of their site should consider using FitVids, especially if they are embedding video content that is already featured on sites like YouTube.

Even though modern HTML5 coding makes it easy to embed your own videos from your disk or device, it is still worth using a plugin like FitVids so you can be flexible with the video content on your site.

The Pros And Cons Of The ZK Framework For Java

By Adam Shrum, IT Manager and analyst at Dynamic CAFM, a Texas based facilities management software provider.

When tackling a new software development project there are many things to consider. First, what is the scope of the project? Second, what language should be used to develop the project. And Finally, what tools will be needed to complete the project efficiently. I manage a team of developers in Pearland, TX and we have had to answer all three of these questions at one time or another. Before we use any tool we always come up with a pros vs. cons analysis to evaluate the tool beforehand. One of the Java tools we use quite frequently is ZK or ZKoss, an Ajax + Mobile enterprise framework that incorporates Spring, JPA, Hibernate, JavaEE, Grails, and Scala. I like to think of ZK as a front end tool that keeps you from having to create a UI from scratch. Like any other front end tool there are pros and cons of using a framework like ZK.

The number one pro of ZK is that it’s Open Source. Because it’s an open source product there is a community of developers that support it via the ZK Forums. It’s important to also note that the documentation for ZK is very good, and there have been few times when we have even needed to go to the forums for help. Another pro is that Big Name Companies use ZK which is always a positive. Companies such as Sony, Deutsche Bank, Sun Microsystems, IBM, Toyota, and Adobe are ZK users and to me one of the biggest red flags of a software tool is that nobody is using it. With ZK you know you’re dealing with a proven product that actually works. ZK has a Rich Modular UI which is made up of many different components you can call out without having to code from scratch. They have thought of almost everything out of the box, but additional components are included with the PE and EE paid versions of the product.
Oh yeah, I forgot to mention that ZK is a Free Product when you use the community edition. Because it’s free there is no upfront cost which is another positive, and there is no cost for a user license as well. If you are working with a legacy system and have decided to utilize ZK in an update to that legacy system you will experience much more control over the system than you had before.

Telephone Hacking

Is Outdated Java Lurking in Your System?

In January of 2013, Oracle announced plans to reevaluate and strengthen its security protocols. The announcement came after serious vulnerabilities were found in Java 6, coupled with widespread criticism of the company’s rigid patch release schedule.

Throughout the next six months, Oracle did, indeed, take steps to tighten their security, surprising some detractors with their commitment to the issue. Most, if not all, security improvements, however, centeron the latest version of Java, Java 7.

Unfortunately, as a recent report by security firm Bit9 makes clear, many organizations continue to use Java 6, forwhichOracle stopped providing public security updates in April of 2013. Even worse, many endpoint systems run multiple versions of Java, which allows hackers to capitalize on older vulnerabilities.

Java Usage and Version Statistics

Bit9 surveyed over 400 organizations, representing a total of over 1 million distinct endpoint systems. The survey discovered Java 6 on over 80 percent of systems. Matters got worse. The most commonly installed version of Java 6 was Java 6 Update 20, which includes a staggering 215 security issues. How far behind is this update? The last version of the software was Java 6 Update 45.

Any system using outdated versions of Java 6 is at risk of serious vulnerabilities. Whether you’re selling 1994 mustang parts or offering online cloud hosting, outdated versions of Java, or indeed any program, represents significant risk of security breaches.

Only 15 percent of endpoint systems surveyed used Java 7, and even then, were rarely up-to-date. Only 3 percent were running Java 7 Update 21, the most recent update at the time of the survey.

What You Need to Know About The Recent Java Patches

The latest round of Java patches, which were released in mid-June, call attention to some issues that all Java programmers should be concerned about. Oracle enabled online certificate revocation checking by default in the move, and it dealt with 40 security issues in Java. Of course, it’s hardly unusual for Oracle to issue a large number of patches at once, but it’s critical that programmers understand what the issues were, whether they maintain sites about British history or alcoholrecovery centers.

Who and What Was Impacted

According to Oracle, 34 of the patches in the Java 7 Update 25 (Java 7u25) affected only client developments of Java. Client and server deployments were affected by four other vulnerabilities, while one dealt with the Java installer and another with the Javadoc tool employed to make HTML documentation files.
Here’s an alarming development: The client-only vulnerabilities, which accounted for the aforementioned 34 patches, were extreme. Oracle graded them highly on its vulnerability severity scale. That’s because they might be used to trick users into loading malicious Java applets onto remote servers, a big problem indeed.
