Java Swing JTable; Right Click Menu (How do I get it to “select” aka highlight the row)

like this:

table.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseReleased(MouseEvent e) {
        int r = table.rowAtPoint(e.getPoint());
        if (r >= 0 && r < table.getRowCount()) {
            table.setRowSelectionInterval(r, r);
        } else {
            table.clearSelection();
        }

        int rowindex = table.getSelectedRow();
        if (rowindex < 0)
            return;
        if (e.isPopupTrigger() && e.getComponent() instanceof JTable ) {
            JPopupMenu popup = createYourPopUp();
            popup.show(e.getComponent(), e.getX(), e.getY());
        }
    }
});
