Apart from this, there are also some excellent features which play an important role in the popularity of this language. The features of Java are also known as. In this article, you will learn about the fundamental features of Java programming language. It's like you need to learn the alphabet before. Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform-independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever.

Java Language is Platform Independent means program of java is Easily transferable because after Compilation of java program bytes code will be created then we have to just transfer the Code of Byte Code to another Computer. This is not necessary for computers having same Operating System in which the code of the java is Created and Executed After Compilation of the Java Program We easily Convert the Program of the java top the another Computer for Execution. Java is Distributed Language Means because the program of java is compiled onto one machine can be easily transferred to machine and Executes them on another machine because facility of Bytes Codes So java is Specially designed For Internet Users which uses the Remote Computers For Executing their Programs on local machine after transferring the Programs from Remote Computers or either from the internet. You can read and write objects on the remote sites via URL with the same ease that programmers are used to when read and write data from and to a file. This helps the programmers at remote locations to work together on the same project.

The portability actually comes from architecture-neutrality. In Java, it has been simplified. For example, an int in Java is always a bit integer, and float is always a bit IEEE floating point number. These consistencies make Java programs portable among different platforms such as Windows, Unix and Mac. Unlike most of the programming languages which are either complied or interpreted, Java is both complied and interpreted The Java compiler translates a java source file to bytecodes and the Java interpreter executes the translated byte codes directly on the system that implements the Java Virtual Machine.

These two steps of compilation and interpretation allow extensive code checking and improved security. Java programs are complied to portable intermediate form know as bytecodes, rather than to native machine level instructions and JVM executes Java bytecode on.

What are the major features of Java programming?

Any machine on which it is installed. Although in the early releases of Java, the interpretation of by bytecode resulted in slow performance but the advance version of JVM uses the adaptive and Just in time JIT compilation technique that improves performance by converting Java bytecodes to native machine instructions on the fly.

Dinesh authors the hugely popular Computer Notes blog. Where he writes how-to guides around Computer fundamental , computer software, Computer programming, and web apps. Java is designed to be easy to learn.

If you understand the basic concept of OOP Java, it would be easy to master. With Java's secure feature it enables to develop virus-free, tamper-free systems.

Authentication techniques are based on public-key encryption. Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system.

Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Java makes an effort to eliminate error-prone situations by emphasizing mainly on compile time error checking and runtime checking.

With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. This design feature allows the developers to construct interactive applications that can run smoothly.

Everything related to storage is predefined, example: But, Java enables high performance with the use of just-in-time compiler.

Below mentioned are some of the core upgrades done as a part of Java 8 release. Just go through them quickly, we will explore them in details later. Ruby Servlet JSP.
