It comes in different flavors:
- Java Standard Edition (Java SE)
This is the plain vanilla version of Java. You can implement any software application with it. Java SE has a large library of code which includes many reusable software functions. Java EE and Java ME described below are built on top of Java SE.
- Java Enterprise Edition (Java EE)
This flavor of Java builds on Java SE. Java EE contains additional libraries of code and development tools that are uniquely useful in developing business applications.
- Java Micro Edition (Java ME)
Than being yet another extension to Java SE, this is in fact a reduced version of Java SE and an associated library of software that addresses the unique needs of Java applications that should run on limited capability devices like mobile phones and PDAs
