Java基于swing实现的弹球游戏代码

本文实例讲述了java基于swing实现的弹球游戏代码。分享给大家供大家参考。

主要功能代码如下:

复制代码 代码如下:

package Game;

import java.awt.Graphics;

import java.awt.Insets;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.util.ArrayList;

import java.util.Random;

import javax.swing.ButtonGroup;

import javax.swing.JMenu;

import javax.swing.JMenuBar;

import javax.swing.JMenuItem;

import javax.swing.JOptionPane;

import javax.swing.JRadioButtonMenuItem;

        }

        /**

         * 得到命令的方法

         */

        public String getCommand() {

                return command;

        }

}

复制代码 代码如下:

package Game;

import java.awt.Color;

import java.awt.Graphics;

import java.awt.event.MouseAdapter;

import java.awt.event.MouseEvent;   

/**

 * 鼠标监听器的类

 * 

 * @author Administrator

 * 

 */ 

public class Listener extends MouseAdapter { 

    private Graphics g; 

    private int x = 5, y = 620; 

    private int width = 100, height = 10; 

 

    public Listener(Graphics g) { 

        this.g = g; 

    } 

 

    public void mouseMoved(MouseEvent e) { 

        // 设置画布对象颜色 

        synchronized (this.g) { 

            g.setColor(Color.black); 

            g.fillRect(x, y, width, height); 

            x = e.getX(); 

            g.setColor(java.awt.Color.green); 

            g.fillRect(x, y, width, height); 

        } 

    } 

 

    /**

     * 得到x的方法

     * 

     * @return:x

     */ 

    public int getX() { 

        return x; 

    } 

 

}

运行效果如下图所示:
