	JButton b4=new JButton("4");
	JButton b5=new JButton("5");

        JButton b7=new JButton("7");
	JButton b8=new JButton("8");
        JButton b9=new JButton("9");
		
	f.add(b1);f.add(b2);f.add(b3);f.add(b4);f.add(b5);
	f.add(b6);f.add(b7);f.add(b8);f.add(b9);

	f.setLayout(new GridLayout(3,3));
	//setting grid layout of 3 rows and 3 columns

	f.setSize(300,300);
	f.setVisible(true);
}
