Java is now a well
know programming language in the world of computers. Its applications range
from mobile devices to large complicated machines.
Java
was developed by James Gosling & Sun Microsystems (now owned by Oracle
Corporation). James Gosling, Mike
Sheridan and Patrick Naughton
started the java project in June 1991 for interactive television. It was
initially called as “Oak”, named after a Oak tree that stood outside Goslings
office. Java is developed from taking many of the features of C and C++
language.
Java is very famous
for its quotation i.e. “Write Once Run Anywhere (WORA)”. This nature of java
programs makes it very popular. With the release of Java 2, it has been divided
into 3 main sub categories,
- J2SE (Java 2 Standard Edition)
- J2EE (Java 2 Enterprise Edition)
- J2ME (Java 2 Micro Edition)
J2SE or Java Se

platform used to deploy portable applications for general use.
J2EE or Java EE
It is a java
platform that is used to deploy sever programming. It is different from Java SE
as it is used to deploy large java softwares running on an application server.
J2ME or Java ME
It is a java
platform that is designed for embedded systems like mobile phones.
