import java.awt.*;

	public class Test1 extends Applet

    public void paint(Graphics g)
    {
    int x=2 ,y=1;
    switch(x + y)
    {
    case 1:
    g.setColor(Color.red);g.drawString("i am 1",5,10);
    break;
    case 2:
    g.setColor(Color.blue); g.drawString("i am2" ,5,10);
    break;
    case 3:
    g.setColor(Color.red); g.drawString("i am 3" ,5,10);
    break;
    default:
