import java.awt.Button;
import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.applet.*;
import javax.swing.Button;
class Main extends Applet implements ActionListener{

Button bSmile;
Button bSleep;
int x=0;
public void init() {
Main app1=new Main();
app1.setSize(200,300);
Container contArea=new Container();
app1.add(contArea);
FlowLayout fl=new FlowLayout(FlowLayout.CENTER);
contArea.setLayout(fl);
bSmile=new Button("Smile");
bSleep=new Button("Sleep");
bSmile.addActionListener(this);
bSleep.addActionListener(this);
contArea.add(bSmile);
contArea.add(bSleep);
showStatus(getAppletInfo());
}

public void actionPerformed(ActionEvent e) {
if(e.getActionCommand()=="Smile")
{
x=0;
repaint();
}
else if (e.getActionCommand()=="Sleep")
{
x=1;
repaint();
}

}
public void paint(Graphics g)
{
g.drawOval(100,50,100,100);
if (x==0)
{
g.drawOval(100,50,100,100);
g.drawLine(125,125,175,125);
g.drawLine(225,125,275,125);
}
else if(x==1)
{
g.drawOval(100,50,100,100);

}
else
g.drawString("Error",70,130);
}

}
