2 Answer

Java is called a platform independent language because compiled Java code (called bytecode) can run on any operating system or hardware platform that has a Java Virtual Machine (JVM).  Some Key Reasons Java is Platform Independent are mention below:

  • Compilation to Bytecode: When you compile Java code (.java files), it gets converted into bytecode (.class files), not directly into machine code.
  • JVM Executes Bytecode: The bytecode is executed by the JVM, which is available for different platforms (Windows, Linux, macOS, etc.). This means the same bytecode can run on any system with a compatible JVM.
  • "Write Once, Run Anywhere": Because of the JVM, Java developers can write code once and run it anywhere—without needing to recompile for different platforms.

Java is called a platform-independent language because Java programs can run on any device that has the Java Virtual Machine (JVM). The code is written once and can run anywhere without needing to be changed this is called "Write Once, Run Anywhere".
