Solution

Java is platform independent because of its two-step execution process: compilation and interpretation.

  1. Compilation: Java code is written in a human-readable format, which is then compiled by the Java Compiler into bytecode. This bytecode is a platform-independent code because it can be run on any machine, regardless of the underlying hardware and operating system. This is unlike other programming languages such as C or C++, which compile code into machine language that is specific to a certain type of hardware.

  2. Interpretation: The Java Virtual Machine (JVM) interprets this bytecode and converts it into machine language during runtime. The JVM is platform-dependent, meaning there is a specific JVM for each operating system. This allows the same Java bytecode to be interpreted and executed on any machine that has the appropriate JVM installed.

So, the combination of bytecode and the JVM allows Java to be platform independent. The code can be written once and run anywhere - this principle is often abbreviated as WORA.

Computer programs are very closely tied to the specific hardware and operating system theyrun. A Windows program will not run on a computer that only runs DOS. A Mac applicationcan’t run on a UNIX workstation. VMS code can’t be executed on an IBM mainframe, andso on. How does java resolve this platform problem?

The idea behind Java’s creation was revolutionary. At that time, most languages were compiled to platform-specific machine code. In contrast, Java is compiled into bytecode that runs on the Java Virtual Machine (JVM), a software-based engine that translates the bytecode into machine code at runtime. This key feature allows Java programs to be written once and run anywhere, a concept abbreviated as WORA. It eradicated the hefty task of rewriting code for different platforms, making software development more streamlined and efficient.
