这篇文章主要介绍了java如何实现一个桌球小游戏，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

具体内容如下

在ecplise中新建一个JAVA项目

建立四个class分别对应游戏登陆界面，游戏界面，数据库操作，和一个开始类

代码如下

游戏类：

package 弹球游戏;import java.awt.BorderLayout;import java.awt.Canvas;import java.awt.Color;import java.awt.Dimension;import java.awt.Font;import java.awt.Frame;import java.awt.Graphics;import java.awt.Panel;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.event.KeyAdapter;import java.awt.event.KeyEvent;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;import java.util.Random;import javax.swing.JTextPane;import javax.swing.Timer;/*----------------游戏界面，弹球游戏------------------*/public class Game { private final int FRAME_X =500; private final int FRAME_Y =450; private final int FRAME_WIDTH =500; private final int FRAME_HIGH =500; private final int TABLE_WIDTH = 100;   //板子宽度 private final int TABLE_HIGH =20 ;   //板子高度 private final int BALL_SIZE =20;   //球的大小 Random rand = new Random(); private int TABLE_X=rand.nextInt(200);  //板子的坐标 private int TABLE_Y=400; private int BALL_X=10;      //小球的横坐标 private int BALL_Y=10;      //小球的纵坐标 private int SPEED = 10;      //小球横向速度 Frame f = new Frame("弹球游戏"); private Mycanvas draw = new Mycanvas(); private boolean is_X = true;   //为true的时候横坐标+ private boolean is_Y = true;   //为true的时候纵坐标+ private int score =0;     //游戏的得分 private Panel p = new Panel(); private JTextPane tex = new JTextPane(); //排行榜显示 //定义键盘监听器 KeyAdapter keyProcessor = new KeyAdapter() {  public void keyPressed(KeyEvent e) {   if(e.getKeyCode()==KeyEvent.VK_LEFT&&TABLE_X>0) {    TABLE_X -=10;   }   if(e.getKeyCode()==KeyEvent.VK_RIGHT&&TABLE_X<370){    TABLE_X +=10;   }   if(e.getKeyCode()==KeyEvent.VK_UP&&TABLE_Y>0) {    TABLE_Y -=10;   }   if(e.getKeyCode()==KeyEvent.VK_DOWN&&TABLE_Y<430) {    TABLE_Y +=10;   }  } }; //定义事件监听器 ActionListener task = new ActionListener (){   public void actionPerformed(ActionEvent e) {    if(BALL_X>FRAME_X||BALL_Y>FRAME_Y&&BALL_Y>TABLE_Y-15) {     try {     DataBaseLoding d = new DataBaseLoding();     d.initParam("mysql.ini");     d.insertScore(score);    } catch (Exception e1) {     e1.printStackTrace();    }     System.out.println("结束了");     timer.stop();    }    if(is_X) {     BALL_X +=10;    }else {     BALL_X -=10;    }    if(BALL_X>440){    is_X=false;     }    if(BALL_X<10) {     is_X=true;    }    if(BALL_Y<0) {     is_Y =true;    }    if(is_Y) {     BALL_Y+=10;    }else {     BALL_Y-=10;    }    if(BALL_Y==TABLE_Y-10&&BALL_X>TABLE_X&&BALL_X登陆类：输入一个名字，成功后就直接开始游戏
package 弹球游戏;import java.awt.Dimension;import java.awt.Graphics;import java.awt.Image;import java.awt.TextField;import java.awt.event.ActionEvent;import javax.swing.AbstractAction;import javax.swing.Action;import javax.swing.ImageIcon;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JPanel;/*-----------------登陆界面,输入名字--------------------*/public class Langding { private final int FRAME_X =500; private final int FRAME_Y =450; private final int FRAME_WIDTH =500; private final int FRAME_HIGH =500; private JFrame f; private JButton ok; private JPanel p; private TextField name; private TextField pass; private Game g; private int score=0; /*-------------暂时还没用到这个*/ //private String PASS_WORD =""; private String NAME_WORD =""; public void init() throws Exception {  f = new JFrame("登陆窗口");  p = new JPanel() {   protected void paintComponent(Graphics g) {   ImageIcon icon = new ImageIcon("lib/01.png");   Image img = icon.getImage();   Image img1 = img.getScaledInstance(FRAME_WIDTH+300, FRAME_HIGH,Image.SCALE_DEFAULT);   icon.setImage(img1);   g.drawImage(img, 0, 0, icon.getIconWidth(),   icon.getIconHeight(), icon.getImageObserver());   }   };  f.add(p);  ok = new JButton("登陆");  name = new TextField(20);  //pass = new TextField(20);  p.add(name);  //p.add(pass);  ok.setPreferredSize(new Dimension(100, 100));  p.add(ok);  //点击按钮的事件  Action go = new AbstractAction() {   public void actionPerformed(ActionEvent e) {    DataBaseLoding d = new DataBaseLoding();    try {     //获得输入的名字     NAME_WORD = name.getText();     //将名字导入到数据库     d.initParam("mysql.ini");     d.insertName(NAME_WORD);    } catch (Exception e1) {     // TODO Auto-generated catch block     e1.printStackTrace();    }    System.out.println("玩家名字是"+name.getText());    //游戏开始    g = new Game();    g.init();   }  };  ok.addActionListener(go);  f.setBounds(FRAME_X, FRAME_Y, FRAME_WIDTH+300, FRAME_HIGH);  f.add(p);  f.setVisible(true); } public static void main(String[] args) throws Exception {  Langding l = new Langding();  l.init(); }}
数据库操作类：包含两个方法，插入名字和修改分数，用的数据库分数默认是-1
package 弹球游戏;import java.io.FileInputStream;import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.Statement;import java.util.Properties;/*------------------------ 数据库的连接和插入名字，修改分数的方法--------------------------------------*/public class DataBaseLoding { private String driver; private String url; private String user; private String pass; //登陆数据库 public void initParam(String paramFile) throws Exception {  Properties props = new Properties();  props.load(new FileInputStream(paramFile));  driver = props.getProperty("driver");  url = props.getProperty("url");  user = props.getProperty("user");  pass = props.getProperty("pass"); } //将名字插入到数据库中 public int insertName(String Name) throws Exception {  Class.forName(driver);  String sql ="insert into 弹球游戏(name) values("+"'"+Name+"'"+")"+";";  try (   Connection conn =DriverManager.getConnection(url,user,pass);   Statement stmt =conn.createStatement();   )  {   System.out.println(Name);   return stmt.executeUpdate(sql);  } } //把score插到主键为name的那一行 public int insertScore(int Score) throws Exception {   Class.forName(driver);   String sql ="update 弹球游戏 set score ="+Score      +" where score = -1"+";";   try (    Connection conn =DriverManager.getConnection(url,user,pass);    Statement stmt =conn.createStatement();    )   {    System.out.println(Score);    return stmt.executeUpdate(sql);   }  } public String select() throws Exception{  Class.forName(driver);  String sql ="select * from 弹球游戏 ORDER BY score DESC ;";  String result ="";  try (    Connection conn =DriverManager.getConnection(url,user,pass);    Statement stmt =conn.createStatement();    ResultSet rs =stmt.executeQuery(sql);    )   {    int i=1;    while(rs.next()) {     result +="第"+i+"名"+ rs.getString(1)+"\t"+"\t"+rs.getInt(2)+"\r";     i++;     if(i==11) {      break;     }    }    return result;   } }}
主类：
package 弹球游戏;public class Begain { public static void main(String[] args) throws Exception {  Langding l = new Langding();  l.init()package 弹球游戏; } }
