Java游戏练习—打地鼠

先看一下样子吧

这里写图片描述

然后是代码
package cn.hncu.games;

import java.awt.Cursor;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Point;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.util.Date;
import java.util.Random;

import javax.swing.BorderFactory;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.SwingConstants;
import javax.swing.Timer;
import javax.swing.border.BevelBorder;

/*
 * 一、显示图片(图像)
 * 1. JLabel: 构造方法 JLabel(Icon image) 
 * 2. Icon接口: 有一个实现类ImageIcon，它的构造方法是ImageIcon(String filename) 

       二、设置鼠标
 * 3. Window类中的一个方法: public void setCursor(Cursor cursor)
 * 
 * 4.java.awt.Toolkit抽象类中的方法
	 1)创建自定义光标: public Cursor createCustomCursor(Image cursor, Point hotSpot, String name)
     2)创建Image对象: public abstract Image createImage(String filename)
     3)创建一个Toolkit对象: public static Toolkit getDefaultToolkit()
   5. Image是表示图形图像的所有类的超类
   
       三、分层显示
   1. 通过JFrame中的方法" JLayeredPane getLayeredPane() ",获得一个分层面板
   2. 在分层面板中添加对象即分层显示: add(Component comp, int index)---把组件comp加在分层面板的index位置，如果index值越小放在越低层
   3. 分层显示时需把内容窗格设成透明(用的是JComponent中的方法)：public void setOpaque(false)
