Java Platform Independency refers to the ability of Java programs to run on any Operating system without any modification in the code. Java compiled code(byte code) can run on all operating systems. JVM depends on the operating system – so if you are running Mac OS X you will have a different JVM than if you are running Windows or some other operating system. So JVM is platform-dependent while JAVA is platform-independent.

How it works?

  1. Java source code is compiled into bytecode by the Java compiler (javac), which is platform-neutral and generates bytecode instructions that can run on any platform.
  2. bytecode is then executed by the Java Virtual Machine (JVM), which is platform-specific but provides a consistent runtime environment for executing Java programs. So bytecode generated from Windows machine can be executed by the JVM on Mac machine.
  3. JVM translates bytecode instructions into machine code specific to the underlying hardware and operating system at runtime, allowing Java programs to run on any platform that has a compatible JVM installed. Every system has its own JVM which gets installed automatically when the JDK software is installed.

Benefits

  1. Portability: Java programs can be developed and deployed across different platforms without modification, reducing the need for platform-specific versions of the software.
  2. Compatibility: Java applications behave consistently across different platforms, ensuring a uniform user experience regardless of the underlying hardware or operating system.
  3. Flexibility: Developers can write Java code once and run it anywhere, streamlining the development process and reducing maintenance efforts.
