Why Java Programs Are Highly Portable?

Java byte code being the same on all computers allows compiled Java programs to be highly portable. But what does highly portable mean in this context?

Portability in Java Programs

High portability: This means that Java programs can run without the need for re-compilation on any computer or platform that supports Java. The concept of portability in Java is often referred to as WORA (Write Once Run Anywhere).

Java Byte Code and Java Virtual Machine (JVM)

Software applications written in Java are compiled into bytecode (.class files), which are designed to run on the Java Virtual Machine (JVM). The JVM acts as a platform-independent layer that interprets the bytecode and executes the Java program regardless of the underlying operating system or hardware architecture.

Because Java byte code is the same across all systems, it eliminates the need for developers to recompile their code for each different machine or operating system. This level of portability makes Java a popular choice for developing cross-platform applications.
