devices like TV, VCR,Theater and each other electronic machines.
The language simple,portable and highly reliable.
The java team where included Patrick naughton discovered that the existing
languages like c and c++ had limitations in terms of both reliability and
portability.
YEAR
DEVELOPMENT
1990
Sun Microsystems decided to develop special software that
could be used to manipulate consumer electronic devices.
Ateam of sun micro systems programmers headed by James
Goastling was formed to under take this task.
1991
The team announced a new language named “Oak”.
1992
The team known as green project team by sun demonstrated
the application of their new language to control a tut of home
