Getting the Selected Items in a JList Component</h3>
The following methods return the indices of the selected items:
<pre>
// To create a list, see <a href="../javax.swing/list_List.html" class="eglink"><font size="-1"><b>e778</b> Creating a JList Component</font></a>
// Get the index of all the selected items
int[] selectedIx = <font color="#0066ff"><i>list</i></font>.getSelectedIndices();
// Get all the selected items using the indices
for (int i=0; i<selectedIx.length; i++) {
Object sel = <font color="#0066ff"><i>list</i></font>.getModel().getElementAt(selectedIx[i]);
}
// Get the index of the first selected item
int firstSelIx = <font color="#0066ff"><i>list</i></font>.getSelectedIndex();
// Get the index of the last selected item
int lastSelIx = <font color="#0066ff"><i>list</i></font>.getMaxSelectionIndex();
// Determine if the third item is selected
int index = <font color="#0066ff"><i>2</i></font>;
boolean isSel = <font color="#0066ff"><i>list</i></font>.isSelectedIndex(index);
// Determine if there are any selected items
boolean anySelected = !<font color="#0066ff"><i>list</i></font>.isSelectionEmpty();
</pre>
The following methods return the selected item objects:
<pre>
// Get the first selected item
Object firstSel = <font color="#0066ff"><i>list</i></font>.getSelectedValue();
// Get all selected items without using indices
Object[] selected = <font color="#0066ff"><i>list</i></font>.getSelectedValues();
</pre>
