java实现一个桌球小游戏

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------------------*/

   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;

 }
 }
