Getting the Selected Items in a JList Component

The following methods return the indices of the selected items:
// To create a list, see Creating a JList Component // Get the index of all the selected items int[] selectedIx = list.getSelectedIndices(); // Get all the selected items using the indices for (int i=0; i<selectedIx.length; i++) { Object sel = list.getModel().getElementAt(selectedIx[i]); } // Get the index of the first selected item int firstSelIx = list.getSelectedIndex(); // Get the index of the last selected item int lastSelIx = list.getMaxSelectionIndex(); // Determine if the third item is selected int index = 2; boolean isSel = list.isSelectedIndex(index); // Determine if there are any selected items boolean anySelected = !list.isSelectionEmpty();
The following methods return the selected item objects:
// Get the first selected item Object firstSel = list.getSelectedValue(); // Get all selected items without using indices Object[] selected = list.getSelectedValues();
