Java™ is a technology developed by Sun Microsystems.
Similar to the way you would download the Java Applet using the
standard Netscape or MS Internet Explorer browsers, Java
MIDlet can be downloaded using the WAP enabled phone.
Depending on the service provider, all Java based programs
such as Java games can be downloaded and run on a phone.
Once downloaded, the Java program can be viewed in the
menu where you can select, execute, or delete.
The Java program files saved in the phone are in .JAD or .JAR
format.
The JAR file is a compressed format of the Java program and
the JAD file is a description file that includes all detailed
information. From the network, prior to download, you can view
all detailed file descriptions from the JAD file.
Only J2ME (Java 2 Micro Edition) based programs will run
in a phone environment. The J2SE (Java 2 Standard
Edition) based programs will only run in a PC environment.
