Creating a JList Component
By default, a list allows more than one item to be selected. Also,
the selected items need not be contiguous. To change this default,
see Setting the Selection Mode of a JList Component.
A list selection event is fired when the set of selected items
is changed (see Listening for Changes to the Selection in a JList Component).
The items can be arbitrary objects. The toString() method of the
objects is displayed in the list component.
By default, a list does not automatically display a scrollbar when
there are more items than can be displayed.
The list must be wrapped in a scroll pane:
// Create a list with some items
String[] items = {"A", "B", "C", "D"};
JList list = new JList(items);
// Create a list with two items - "123" and "Sun May 19 21:15:38 PDT 2002"
Object[] items2 = {new Integer(123), new java.util.Date()};
list = new JList(items2);
JScrollPane scrollingList = new JScrollPane(list);
