Java is a simple and yet powerful object oriented programming language.

The Java virtual machine (JVM) is a software implementation of a computer that executes programs like a real machine.

Java is created by James Gosling from Sun Microsystems (Sun) in 1991. The first publicly available version of Java (Java 1.0) was released in 1995.
