J2SE Introduction :What is J2SE
J2SE is a collection of Java Programming Language API (Application programming interface)
that is very useful to many Java platform programs. It is derived from one of the most
dynamic programming language known as "JAVA". Java is the creation of Sun Microsystems.
and one of its three basic editions of Java known as Java standard edition being used for
writing Applets and other web based applications.
Java has advanced through the years in both functionality and reach. Current editions are on
the Java 2 Platform. The Java 2 Platform has various incarnations as well, including Java 2
Platform.
The Java 2 Platform has three basic Editions
Java 2 Standard Edition (J2SE): J2SE is used primarily for writing applets and other Java-based
applications.
Java 2 Enterprise Edition (J2EE): J2EE is the Java architecture for developing multitier
enterprise applications. As part of J2EE, JSP pages have access to all J2EE components,
including JavaBeans and Enterprise JavaBeans components and Java servlets. JSP pages are
actually compiled into servlets, so they have all of the benefits of these flexible, server-side
Java applications.
Java 2 Micro Edition (J2ME): J2ME is a technology that allows programmers to use the java
programming language and related tools to develop programs for mobile wireless
information devices such as cellular phones and personal digital assistants (PDAs).
One of the primary uses of J2SE is the development of Java applications for individual
computers. Web-based activity sometimes lives and dies by the successful integration of
applets into e-commerce and other Web-specific functions.Applet is a type of fast-working
subroutine of Java that is platform-independent but work within other frameworks. It is a
mini applications that perform a variety of functions, large and small, ordinary and dynamic,
within the framework of larger applications.

J2SE platform has been developed under the Java umbrella and primarily used for writing
applets and other Java-based applications. It is mostly used for individual computers. Applet
is a type of fast-working subroutine of Java that is platform-independent but work within
other frameworks. It is a mini applications that perform a variety of functions, large and
small, ordinary and dynamic, within the framework of larger applications.
J2SE provide the facility to users to see Flash movies or hear audio files by clicking on a Web
page link. As the user clicks, page goes into the browser environment and begin the process
of launching application-within-an-application to play the requested video or sound
application. So many online games are being developed on J2SE. JavaBeans can also be
developed by using J2SE.
Another important functionality made possible by J2SE is JavaBeans. These are reusable
applications that can be developed and assembled easily in order to create more
sophisticated applications. Basically, they are the building blocks of personalized J2SE
applications. Java may be the base technology, but JavaBeans are what makes J2SE
functionality and individuality really click.
