The Java programming language is based on the virtual machine concept. A program written in the Java language is translated by a Java compiler into Java byte code. The latter is a low-level language that is quickly executed at run time by a program known as a Java virtual machine (JVM). The JVM has been implemented on many different computer systems, making Java programs relatively system-independent.
