J2ME is used to develope the applications to run on mobile devices. J2ME application uses Java compiler, WTK and obfuscator to preverify the classes, package into jad, jar files.
J2ME is similar to java application with some slight changes in the syntax. In J2ME instead of main method, it contains a MIDlet class, which starts the application. Each J2ME application contains one MIDlet class.
Set up development environment:
- Sun Wireless Tool Kit (WTK) to run the application on simulator.
- EclipseME
