To achieve its goal of Write once, run anywhere, Java does both: a Java compiler converts Java code into machine-readable bytecode, then the Java Virtual Machine interprets the code for the computer it runs on.ndividual computers often use different machine languages, so if you compiled a Java program to a single machine language, the compiled program would not be able to run on multiple machines. To solve this problem, the Java Virtual Machine is a simulated machine which has multiple implementations for each computers.
