CHAPTER 4

Using the Emulator

The J2ME Wireless Toolkit emulator simulates a MIDP device on your desktop computer. It is a convenient way to see how your application performs in a MIDP environment and gives you a tight development cycle that is entirely contained on your desktop computer.

The emulator does not represent a specific device, but it provides correct implementations of its supported APIs.

4.1Emulator Skins

A skin is a thin layer on top of the emulator implementation that provides it with a certain appearance, screen characteristics, and input controls. The J2ME Wireless Toolkit comes with skins that represent different kinds of devices.
