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.
4.1 Emulator 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.
You can create your own emulator skins if you wish. See the Basic Customization
Guide for details.
