History of JAVA

                   Actually Java was originally designed for programming consumer devices, but it was first succeful ly used to with internet applets.In the year 1991, when a group of SUN  engineers (which is now subsidiary  of oracle corporation) led by James Gosling,  Patrick Nauton, Mile Sheridon  wanted to design a small computer language that could be used for    consumer devices like, cable TV switch boxes, remote controller, Microwave oven. Because these devices do not have lot of memory the language had to be small and generate very tight code. Also, because different manufacturers may choose different CPUs, it was important that the language not be tied to as single architecture, the project was code-named “Green”.

Later it renamed as “OAK” after an oak tree that stood outside gosling’s office. Then it renamed as JAVA.

Versions history you can find in the wiki:-

When API was growing it because difficult for SUN to Maintain.
