Introduction

The previous articles have described the installation and configuration of Eclipse and its work environment, and have completed the relevant preparations. So from this article, we'll talk about how to use the previously configured Eclipse development environment to create a J2ME project and start a real J2ME development trip. Since this is the first J2ME program to be created, according to the practice of program development, this first place is naturally not "Hello world". HelloWorld, although the function is simple, but though small, spite, through the development of this small program, fully able to make the reader familiar with the J2ME program development of the general flow of the purpose.

Create a J2ME project

Similar to the development of other language applications, it is also necessary to create a new project (engineering) for all subsequent coding, commissioning, and operation in the development of a J2ME program. After you start eclipse, click the Project menu item that pops up on the new menu under the File menu. The New Project Wizard dialog box will pop up as shown below:

First you need to specify what project to create, expand the J2ME project, and select the J2ME Midlet Suite subkey to go to the next step.
