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.

The concept behind the creation of Java was indeed revolutionary. During that period, most programming languages were compiled into machine code that was specific to a particular platform. On the other hand, Java is compiled into bytecode that runs on the Java Virtual Machine (JVM). The JVM is a software-based engine that translates the bytecode into machine code during runtime. This unique feature allows Java programs to be written once and run anywhere, a concept that is abbreviated as WORA. This eliminated the cumbersome task of rewriting code for different platforms, thereby making the process of software development more streamlined and efficient.
