Summary

In this chapter, you learned the history and background of J2ME and the CLDC configuration. We covered the MID and PDA profiles and gave you an overview of some existing software development kits. You should be able to set up the Sun development kits, to compile actual MID and PDA programs, and to run them in the corresponding device emulation.

The following chapters will first describe the Connected Limited Device Configuration (CLDC). Then, we'll revisit the MIDP and PDAP “Hello World” applications from an API point of view and explain the lifecycle of a MIDlet. We will also explain the user interface of MID and PDA applications in depth.
