java实现一个桌球小游戏

作者：ruanwenjun_csdn

这篇文章主要为大家详细介绍了java实现一个桌球小游戏，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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_Y =450;

 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

   System.out.println("结束了");
   timer.stop();

 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;

 }
 }
