The JList Class
The JList class is the generic Swing implementation of a list
component. In the default selection mode, you can make multiple
selections by clicking with the mouse while holding down the modifier key defined by the current L&F (generally
Shift for a single, contiguous range and Ctrl or Command for noncontiguous selections). The JList class does not provide scrolling
capabilities, but it can be set as the viewport of a JScrollPane to support scrolling. Figure
7-8 shows the JList component
in four different L&Fs.

Properties
The JList class essentially
combines the features of the data model, the selection model, and the
cell renderer into a single Swing component. The properties of the
JList class are shown in Table 7-9.
