Selection mode in JTable?

I couldn't understand the difference between multiple_selection_interval and singl开发者_C百科e_interval_selection in JTable.

table.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);

next, is

table.setSelectionMode(ListSelectionModel.MULTIPLE_SELECTION_INTERVAL);

What's the difference these?

With ListSelectionModel.SINGLE_SELECTION you can just select one row. With ListSelectionModel.SINGLE_INTERVAL_SELECTION you can select more than one row, which are in one block. (e.g. you can select row 1 - 5, but not row 1-3 and row 4-6, therefor you need ListSelectionModel.MULTIPLE_INTERVAL_SELECTION)
