How to write your own Java Application?

If you know how to do it, Java is an easy way for writing your own Nokia smartphone applications by using J2ME. You can use the Nokia Developer's Suite for J2ME, which is a free download from the website of Forum Nokia (http://www.forum.nokia.com/). The Nokia Developer's Suite for J2ME is running under Windows, Linux, and offers the following features from a simple graphical user interface (GUI):

• An editor of Java source code
• A drag-and-drop user interface (UI) builder to generate classes of the user interface for the phone application from a visual designer
• Tools for compiling the source code of Java and construct the JAD and JAR for distribution
• Emulators to test your applications on the computer before they are deployed on the physical device. Nokia PC Suite for J2ME comes with a Nokia 6230 emulator and a generic Nokia Series 60 phone emulator. You can download and install other emulators free from the website of Forum Nokia. The Nokia Developer's Suite for J2ME manages all installed emulators.
  

If you are a Java developer and prefer to work with the Integrated Development Environment (IDE) tools, you can install the Nokia Developer's Suite for J2ME inside a popular IDE such as Eclipse. In this way, the J2ME development features in the IDE appear in the menu rather than a graphics.
