icon

请问为什么我没有图标显示,是不是要调用paintIcon()的方法，如果是，怎么调用

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Swing_test extends JFrame{
	public Swing_test(){
		this.setSize(300,150);
		this.setLocation(300,200);
		this.setDefaultCloseOperation(EXIT_ON_CLOSE);
		class MyIcon implements Icon{
			private int width;
			private int heigth;
			public int getIconHeight(){
				return this.heigth;
			}
			public int getIconWidth(){
				return this.width;
			}
			public MyIcon(int width, int height){
				this.width = width;
				this.heigth = heigth;
			}
			public void paintIcon(Component arg0, Graphics arg1, int x, int y){
				arg1.fillOval(x, y, width, heigth);
			}
		}
		MyIcon a = new MyIcon(15,15);
		JLabel label = new JLabel("测试", a, JLabel.CENTER);
		label.setVisible(true);
		this.add(label);
		this.setVisible(true);
	}
	public static void main(String[] ar){
		new Swing_test();
	}
}

 public MyIcon(int width, int height){
                this.width = width;
                this.heigth = height;
            }

构造函数写错了。

[Quote=引用 1 楼 closewbq 的回复:]
Java code

public MyIcon(int width, int height){
this.width = width;
this.heigth = height;
}

构造函数写错了。
