How to select multiple rows in JTable?

Question

How can I handle multiple rows selection in a JTable? here is the code I have been using for selecting only one row:

table1 = new JTable();
        table1.setModel(Ajmodel);
        table1.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
            public void valueChanged(ListSelectionEvent event) {
                selectedAJ_ID = (Integer) table1.getModel().getValueAt(table1.getSelectedRow(), 0);
            }
        });

Thank you in advance.

you can allow multiple selection by jTable.setRowSelectionAllowed(true); jTable.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

and you can get the values by

if (jTable.getSelectedRows() > -1) {

                 int[] selectedrows = jTable.getSelectedRows();

                 for (int i = 0; i < selectedrows.length; i++)
                {

                     System.out.println(jTable.getValueAt(selectedrows[i], 0).toString());

                }

            }

If I set this property, how would I handle the listener? – TiyebM Feb 08 '17 at 15:34
`int[]i=new int[table1.getSelectedRowCount()]; for(int j=table1.getSelectedRow();j – XtremeBaumer Feb 08 '17 at 15:37
you can try `int[] selectedrows = jTable.getSelectedRows();` to get selected rows – U X Feb 08 '17 at 15:40
@UX that returns the index of the rows you selected but not the values – XtremeBaumer Feb 08 '17 at 15:41
@XtremeBaumer @TiMr From the selected indexes values can be get by `jTable.getModel().getValueAt(row_index, col_index);` – U X Feb 08 '17 at 15:43
`int[]i=new int[table1.getSelectedRowCount()]; for(int j=0;j – XtremeBaumer Feb 08 '17 at 15:44
@XtremeBaumer nice tries, but I gess the idea is to parse `table1.getSelectedRows()` as `s int[]` with the implementation of `getValueAt(s[i],0)`, I am testing it now, please consider providing an answer. – TiyebM Feb 08 '17 at 15:53
@TiMr if you add a button and add `JButton showDialogButton = new JButton("Text Button"); showDialogButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { make the readings } });` – U X Feb 08 '17 at 16:02
@UX, Thanks, it works. – TiyebM Feb 08 '17 at 16:27
I am glad :) @TiMr – U X Feb 08 '17 at 16:48
