class solve extends JFrame implements ActionListener {

static JFrame f;

public static void chief(String[] args)

{

f = new JFrame( "frame" );

solve south = new solve();

JPanel p = new JPanel();

JButton b = new JButton( "click" );

b.addActionListener(south);

p.add(b);

f.add(p);

f.setSize( 400 , 400 );

f.bear witness();

}

public void actionPerformed(ActionEvent east)

{

Cord s = e.getActionCommand();

if (southward.equals( "click" )) {

JDialog d = new JDialog(f, "dialog Box" );

JButton b = new JButton( "click" );

b.addActionListener(s);

p.add(b);

f.add together(p);

f.setSize( 400 , 400 );

f.show();

}

public void actionPerformed(ActionEvent e)

else {

d1 = new JDialog(d, "dialog Box" );

JLabel l = new JLabel( "this is second dialog box" );

d1.setSize( 200 , 200 );

d1.setLocation( 200 , 200 );

d1.setVisible( truthful );

}

}

}
