concretesubject.java

这个文件里面包含了java设计模式的一些例子讲解

package com.javapatterns.observerawt.mouse1;

import java.awt.Frame;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;

public class ConcreteSubject  extends Frame implements MouseListener
{
    /**
     * @link aggregation 
     */
    private static MouseListener m;

    public ConcreteSubject()
    {
    }

	public void mouseClicked(MouseEvent e)
    {
		System.out.println(e.getWhen());
	}

    public void mousePressed(MouseEvent e){}

    public void mouseReleased(MouseEvent e){}

    public void mouseEntered(MouseEvent e){}

    public void mouseExited(MouseEvent e){}

	public static void main(String[] argv)
    {
		ConcreteSubject s = new ConcreteSubject();
       ;
		s.setBounds(100, 100, 100 , 100);
		s.addMouseListener(s);
        s.show();
	}
}
