import java.awt.*; import javax.swing.*;

class ButtonFrame extends JFrame { JButton Button1 ; JButton Button2 ; JButton Button3 ; JButton Button4 ;

// constructor for ButtonFrame ButtonFrame(String title) { super( title ); setLayout( new FlowLayout() );

Button1 = new JButton("Button 1"); Button2 = new JButton("Button 2"); Button3 = new JButton("Button 3"); Button4 = new JButton("Button 4"); add( Button1 ); add( Button2 ); add( Button3 ); add( Button4 ); // add the button to the JFrame setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); } }

public class ButtonDemo { public static void main ( String[] args ) { ButtonFrame frm = new ButtonFrame("Basic GUI");

frm.setSize( 400, 80 ); frm.setVisible( true ); } }
