What's wrong with my buttons, any one can figure out?

Question

I am creating a SleeperFace with Applet, there was a problem that my buttons does not appear normally, just when I point the mouse on, then the two buttons will be appeared.
Here are my codes:
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class SleepyFace extends Applet implements ActionListener
int x=0;
public void init()
JButton bAwake=new JButton("Awake");
bAwake.addActionListener(this);
JButton bAsleep=new JButton("Asleep");
bAsleep.addActionListener(this);
add(bAwake);
add(bAsleep);
public void actionPerformed(ActionEvent e)
if(e.getActionCommand()=="Awake")
x=1;
repaint();
else if (e.getActionCommand()=="Asleep")
x=0;
repaint();
public void paint(Graphics g)
setBackground(Color.blue);
g.setColor(Color.yellow);
g.fillOval(50,60,400,400);
g.setColor(Color.black);
if (x==1)
g.fillOval(130,160,50,100);
g.fillOval(312,160,50,100);
g.fillOval(222,250,50,50);
g.fillArc(150,270,200,120,-360,-180);
g.setColor(Color.white);
g.setFont(new Font("SansSerif", Font.BOLD, 24));
g.drawString("Let's make some noise!", 120,520);
else
g.fillRect(100,240,100,4);
g.fillRect(300,240,100,4);
g.fillOval(222,250,50,50);
g.fillRect(150,350,200,4);
g.setColor(Color.white);
g.setFont(new Font("SansSerif", Font.BOLD, 24));
g.drawString("I'm sleeping, please do not disturb!", 50,520);
}

Answer 1

FlowLayout is generally not a good top ContainerLayout.
I am not debating that. I agree BorderLayout is a
better top level LayoutManager (which is why I made
the earlier assumption that Applets also use a
BorderLayout).
I realize that you aren't - in fact, I did not take you to be debatinganything. I added that piece of information merely to explain why I changed the Layout Manager - in order to add the JButtons where I wanted them to be - which is admittedly not where the OP might want them.
I am questioning how using a BorderLayout causes the
children to be painted, even though the paint()
method does not invoke super.paint().
I have not intentionally avoided calling super.paint. As I said, I do not know the real reason. But this has worked before, and I believe it has to do with adding the two JButton Components to another Panel; because if you simply add them BorderLayout.NORTH and BorderLayout.SOUTH it won't help.
