Is Java Platform Independent if then how?

Yes, Java is platform-independent, and this characteristic is a fundamental aspect of the language’s design. Here’s how Java achieves platform independence:

Java Source Code: When you write Java code, it is saved in files with a .java extension. This source code is human-readable and can be written on any platform.

Compilation to Bytecode: When you compile the Java source code using the Java Compiler (javac), it is translated into an intermediate form known as bytecode, which is saved in files with a .class extension. This bytecode is not specific to any hardware or operating system; rather, it is a set of instructions that can be understood by the Java Virtual Machine (JVM).

Java Virtual Machine (JVM): The JVM is a crucial component that makes Java platform-independent. It is a virtual machine that interprets and executes the bytecode on any device or operating system that has a compatible JVM installed. Since the JVM is available for various platforms (Windows, macOS, Linux, etc.), the same bytecode can run on any of them without modification.

“Write Once, Run Anywhere” (WORA): This principle captures the essence of Java’s platform independence. Developers can compile their code into bytecode once, and it can be executed on any platform that has the JVM. This eliminates the need for recompiling code for different platforms, making Java highly portable.
