本文实例为大家分享了java实现桌球小游戏的具体代码，供大家参考，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_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 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

score++;

draw.repaint();

}

};

Timer timer = new Timer(100,task);

public void text() {

}

class Mycanvas extends Canvas{

public void paint(Graphics g) {

g.setColor(new Color(0, 0, 0));

g.drawLine(0, FRAME_Y, FRAME_X-20, FRAME_Y);

g.drawLine(FRAME_X-25, 0, FRAME_X-25, FRAME_Y);

Font font = new Font("分数",10,20);

g.setFont(font);

g.drawString("分数："+score, 380, 20);

}

}

}

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;

}

}
