HISTORY OF JAVA

Java was developed at SUN MICROSYSTEMS by "JAMES GOSLING" and his team.

The trial version was developed and released in the year 1990 was named "OAK" which was later named as java and it took 18 months to develop scientifically. OAK is the name of a tree.

Originally Sun MicroSystems is one of the academic university (Stanford University Network). Sun developed rules for java under the guidance of James Gosling and those rules are programmatically implemented / developed / defined by java soft INC in USA, which is the software division of Sun MicroSystems only.

The software OAK initially solved some of the problems of the industry and yet there were problems not solved. In another words OAK software did not completely solve the problems in the industry. Hence the software OAK was revised by Sun MicroSystems and in the year 1995 it was released to the industry with the name "JAVA".

There are three categories of java namely :

• J2SE - It is used by the industry for the development of Standalone applications.
• J2EE - It is used for developing the server side application to exchange the data between J2SE and J2EE applications. Here we use a protocol called HTTP.
• J2ME - It is used for developing mobiles / wireless applications, by using protocol called WAP (Wireless Access Protocol).
