Java is a object oriented basic language which enables software developers to implement the creative ideas in order to develop user friendly and widely used applications. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.

As of 2016, Java is one of the generally used programming languages, with a reported 9 million developers, mostly for client-server web applications. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core module of Sun Microsystems Java platform. The language derives much of its syntax from C and C++, but it has smaller amount low-level facilities than either of them.

As of 2007, Others have also developed another implementations of these Sun technologies, Iced-Tea-Web (browser plugin for applets), such as the GNU Classpath (standard libraries),  and GNU Compiler for Java (bytecode compiler).

The newest version is Java 10, released on March 20, 2018, which follows Java 9 after only six months in line with the new release schedule. Java 8.0 is still supported but there will be no additional security updates for Java 9.0. Versions previous than Java 8.0 are supported by companies on a commercial basis; e.g. by Oracle back to Java 6 as of October 2017 (while they still “extremely recommend that you uninstall” pre-Java 8 from at least Windows computers).

What is Java Platform?

Java platform is a set of programs that make easy to run and develop programs written in the Java programming language. Java platform includes a compiler, an execution engine and a set of libraries. JAVA is platform-independent language. It is not exact to any processor or operating system.

How is Java Platform Independent?

Like C compiler, Java compiler do not manufacture native executable code for a particular machine. as a substitute, Java produces a unique system called bytecode. It executes according to the policy laid out in the virtual machine specification.

Bytecode is understandable to any JVM installed on any OS. in a word, the java source code can run on all operating systems.

How Java Virtual Machine works?

By using Java Virtual Machine, this problem can be solved. But how it works on different processors and O.S. Let’s understand this procedure step by step.

Step 1) The code to display adding up two numbers is System.out.println(1+2), and saved as .java file.

Step 2) Using the java compiler the code is converted into an transitional code called the bytecode. The output is a .class file.

Step 3) This code is not understand by any platform, but only a virtual platform called the Java Virtual Machine.

Step 4) This Virtual Machine resides in the RAM of your operating system. When the Virtual Machine is fed, it identifies the platform it is functioning on and converts the bytecode into the native machine code.

in reality, while working on your PC or browsing the web whenever you see any of these icons be assured the java virtual machine is loaded into your RAM. Hence, Java is a programming language as well as a Platform


There be five primary goals in the formation of the Java language:

  •   “simple, object-oriented, and familiar”.
  •   “robust and secure”.
  •   “architecture-neutral and portable”.
  •   “interpreted, threaded, and dynamic”.
  •   It execute with “high performance”.

Sun has defined and supports four editions of Java targeting different application environments and segmented many of its APIs so that they belong to one of the platforms.
