Answer:
JList.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION)
Explanation:
JList provides for simultaneous selection of multiple items upon setting the selection mode to MULTIPLE_INTERVAL_SELECTION. The API call for this purpose is:
jlist.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION)
Once the selection mode has been set , we can select set of items in the list as follows:
jlist.setSelectedIndices({1,3,5});
This will select the items with indices 1,3,5 in the list.
