在JPanel中添加不了图片。。。

Question

路径确定没错。图片也存在。。把图片放在JLabel中的
class Expression extends JFrame
{
JCheckBox CheckBox;
JLabel Label;
expressionPanel ep;
public Expression()
{
setSize(452,301);
    setUndecorated(true);
setLayout(null);
ep=new expressionPanel();
getContentPane().add(ep);
setVisible(true);
}
public static void main(String[] args)
{
new Expression();
}
class expressionPanel extends JPanel
{
int x,y;
final private int WIDTH=30,HEIGHT=30;
JLabel label;
public expressionPanel() {
setLayout(new GridLayout(8,15));
setSize(452,241);
for(x=0;x<120;x++)
{
label=new JLabel(new ImageIcon("image/face/"+x+".gif"));
System.out.println("image/face/"+x+".gif");
add(label);
}
}
public void paint(Graphics g)
{
g.setColor(new Color(230,200,151));
for(x=0;x<=450;x=x+30)
for(y=0;y<=240;y=y+30)
g.drawRect(x, y, WIDTH,HEIGHT);
}
}
}

Answer 1

     public void paint(Graphics g)
        {
            g.setColor(new Color(230,200,151));
            for(x=0;x<=450;x=x+30)
                for(y=0;y<=240;y=y+30)
                    g.drawRect(x, y, WIDTH,HEIGHT);
        }
覆盖住了。。
