The StringItem class defines a
two-part display component. StringItem objects
contain a label and some immutable text. The sample J2ME
program shows the pertinent parts of the StringItemDemo
code. You can correlate the text in the constructor's two argument
parameters with the text on the display. This is a very simple UI component.
StringItem objects give you a
convenient way to associate a label with a value. You can put a String in a Form
instead of using a StringItem object, but
the StringItem has the advantage that its implementation ensures that the label and
value strings remain together on the display.
String items are forms.
