Java, in its initial stage is launched as an object oriented programming language, derive out its syntax from C and C++.

With the release of Java 2 around late ninties, different editions are offered which are follows
- Java SE ( Java 2, Standard Edition )
- Java EE ( Java 2, Enterprise Edition )
- Java ME ( Jave 2, Micro Edition )

To understand the difference between Java ( programming language ) and the Java Editions given above, we need to conceptualize platform.

A platform mainly consist of
- Computer Architecture
- Operating System
- Programming Language
- Libraries

The first two points covers the hardware architecture of the platform and last two covers the software framework for the platform. Thus programming language is a just a subset of the platform.

Java Platform consists of the following
- SDK ( JDK + Application Servers + Debuggers + Documentation )
- JDK
   a) Java Language
   b) Java Virtual Machine (JVM)
   c) Java Complier
   d) Java Language Libraries
- Editions
   a) Java Card : Technology that allows small java based applications (applets) to be run securely on smart card
   b) J2ME: Java 2 Micro Edition consist of set of libraries requires for small memory devices like mobile phones
   c) J2SE: Java 2 Standard edition consist of standard set of java libraries for Desktop PC’s, servers and similar devices
   d) J2EE: Java SE + various API useful for multi-tier client–server enterprise applications - Program Execution
   a) Java Compiler complies and convert source code to byte code
   b) The byte code is converted to native machine code by JVM which comes with JDK and JRE
   c) JRE comes with JIT complier in JVM which converts the byte code to machine code on the fly and caches the native code in memory during execution thus improves the execution time to a considerable extent.

Advantages of Java
- Object Oriented
- Robust and Secure
- High Performance
- Portable

J2EE Architecture

J2EE appication components runs within different execution enviroments in J2EE Server called as containers.

• JSP, JSF, Servlets components runs in Web Container
• Enterprise Java Beans runs in EJB Container
• Application Client components run in Application Container
• At the architecture level, J2EE applications mainly follows 3-Tiered architecture having presentation, business and persistence layer.
• Presentation Layer components are used to display the information to the user
• Business Layer components are used to execute the business logic embedded into the application
• Persistence Layer components carries out the database activities for the application

Advantages of J2EE Platform

• Simplified architecture and development
• Freedom of choice in servers, tools, and components
• Integration with existing information systems
• Scalable to meet demand variations
• Flexible security model
• Multi-tiered and distributed applications
