Jav Programming Language And A Development Platform Essay
Java is known as both a programming language and a development platform. It was first developed by Sun Microsystems in 1991 and subsequently released in 1995. To help to make the language more accepted and accessible, Sun Microsystems developed it as an object oriented language with a syntax that is very similar to C++. (Java vs. .NET, 2007) Sun Microsystems decided to create this new platform out of a desire to be able to write programs only once that could be run on any system.(James) In December 1998, the Java 2 platform was launched. This was a major improvement of the platform, and included new graphics, user interface, and enterprise capabilities. This upgrade was over seven times as large as the initial Java 1.0 release and marked the maturity of the Java platform. (What is java?) Within the Java 2 platform there are 3 editions:
• The Java 2 Standard Edition (J2SE)
Provides the essential compiler, tools, runtimes, and APIs for writing, deploying, and running applets and applications.
• The Java 2 Enterprise Edition (J2EE)
Defines a standard for developing multi-tier enterprise applications.
• The Java 2 Micro Edition (J2ME)
Enables Java development on such devices as PDAs and smart phones.

To run a program using the Java language all source code is first written in a text file with the .java extension. The javac compiler then compiles all these source files into a .class file. The .class file is made up of bytecodes which are then…
