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

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;
}
}
