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;

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;

  }
 }
