Java is a general purpose, high-level programming language developed by Sun Microsystems whose one of the co - founder is Indian (Vinod Khosla) . A small team of engineers, known as the Green Team, initiated the language in 1991. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak name was unsuccessful, so in 1995 Sun changed the name to Java. The name JAVA is given from an island which is in Indonesia whose coffee was being supplied to JAVA people.
