这里:
public void paintComponet( Graphics g )
{
super.paintComponent(g);


g.drawString("dddd",50,0);
}
改成:
public void paint( Graphics g )
{
super.paint(g);


g.drawString("dddd",50,50);
}

public void paintComponet( Graphics g )//paintComponet少了一个n
{
super.paintComponent(g);


g.drawString("dddd",50,0);
}
改为
public void paintComponent( Graphics g )
{
super.paintComponent(g);


g.drawString("dddd",50,0);
}
