Lists
A list is a screen of choices. MIDP offers three list types: exclusive-choice, which allows the user to select one and only one element; multiple-choice, which allows the user to select zero or more elements; and implicit, which allows the user to select one element for a subsequent action. Screenshot shows the three list types.
