Using the Emulator Controls
The J2ME Wireless Toolkit emulator appears as a generic mobile phone, as shown in Figure 2-2.

SUN's J2ME Wireless Toolkit emulator exhibits several qualities that you are likely to find
in real devices:
The device has a small screen size and limited input capabilities. (It's not as small as
the earlier J2ME Wireless Toolkit 1.x emulators, which included emulated devices with
96×128 and 96×54-pixel screens.)
Two soft buttons are available. A soft button does not have a fixed function. Generally,
the function of the button at any given time is shown on the screen near the button. In
MIDlets, the soft buttons are used for commands.
Navigation buttons are provided to allow the user to browse through lists or other sets
of choices.
•A select button allows the user to make a choice after moving to it with the navigation
buttons. (Think “Yes, that's my final answer.”)
