This tutorial will show you how create a basic user interface as well as add menu items.
We are going to use Screen, Field, Layout managers and MenuItem classes to create the user
interface which is shown on (Figure 1).

Introduction
You can use standard MIDP APIs and BlackBerry® UI APIs to create BlackBerry® Java Application UIs.
The BlackBerry UI APIs are a library of UI components that are designed to provide default layouts
and behaviours that are consistent with the core BlackBerry device applications.
• Screen components provide a standard screen layout, a default menu, and standard
behaviour when the BlackBerry device user presses the Escape key or clicks the trackwheel
or trackball.
• Field components provide standard UI elements for date selection, options, check boxes,
lists, text fields and labels, and progress bar controls.
• Layout managers provide an application with the ability to arrange components on a
BlackBerry device screen in standard ways, such as horizontally, vertically, or in a left-to-
right flow.
Please note that you can always find more information about the APIs we are using in the BlackBerry
API reference document which is the part of any JDE Component Pack (Figure 2Error! Reference
source not found.). You can find it on your computer under Start / Programs / Research in Motion /
BlackBerry JDE 4.x.
