Evolution of Java Technology
In 1991, James Gosling an engineer of Sun Microsystem and his small team seek for a platform independent language for digital consumer devices and appliances.
They named their team as green team and project as green project. After the hard work of thousands of hours they created a language and named that ‘oak’, a plat in their working yard.
They initially demonstrated the language on the controller for digital cable. But later in 1994 they realise that the language can be used to program with internet.
