Selected Ans.

The Java platform is a set of programs that help developing and running programs written in the Java programming language.

Is that clear ?

Now,the platform is not specific to any one processor or operating system, rather an execution engine (called a virtual machine) and a compiler with a set of libraries are implemented for various hardware and operating systems so that Java programs can run identically on all of them.

There are multiple platforms, each targeting a different class of devices:

  • Java Card: for smart cards and similar small-memory devices.
  • Java ME (Micro Edition): Used to develop applications for mobile devices, PDAs, TV set-top boxes, and printers.
  • Java SE (Standard Edition): For general-purpose use on desktop PCs, servers and similar devices.
  • Java EE (Enterprise Edition): Java SE plus various APIs useful for multi-tier client–server enterprise applications.

Now J2EE :
Java Enterprise Edition from version 1.2 till 1.4 comes under J2EE
Versions from 1.5 are termed Java EE or JEE

Now we have JEE 7 and 8 will be out soon.

Final Note :

Based on the requirements you can change over to updated versions.

J2EE & JEE 7 :
