        JButton bt2= new JButton("Reset");
        JPanel pl= new JPanel(true);
        pl.setLayout(new GridLayout(4,2, 2, 7));
        pl.add(l1);pl.add(ar1);pl.add(l2);
        pl.add(ar2);pl.add(l3);pl.add(ar3);
        pl.add(bt1);

        intfr.setSize(200,200);
        intfr.setVisible(true);
        intfr.setLayout(new FlowLayout());
        dp.add(intfr);
