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;
public class Game {
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 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
private Panel p = new Panel();
private JTextPane tex = new JTextPane(); //排行榜显示
//定义键盘监听器
KeyAdapter keyProcessor = new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if(e.getKeyCode()==KeyEvent.VK_LEFT&&TABLE_X>0) {
TABLE_X -=10;
}
if(e.getKeyCode()==KeyEvent.VK_RIGHT&&TABLE_X<370){
TABLE_X +=10;
}
if(e.getKeyCode()==KeyEvent.VK_UP&&TABLE_Y>0) {
TABLE_Y -=10;
}
if(e.getKeyCode()==KeyEvent.VK_DOWN&&TABLE_Y<430) {
TABLE_Y +=10;
}
}
};
//定义事件监听器
ActionListener task = new ActionListener (){
public void actionPerformed(ActionEvent e) {
if(BALL_X>frame_X||BALL_Y>frame_Y&&BALL_Y>TABLE_Y-15) {
try {
DatabaseLoding d = new DatabaseLoding();
d.initParam("mysql.ini");
d.insertScore(score);
} catch (Exception e1) {
e1.printStackTrace();
}
System.out.println("结束了");
timer.stop();
}
if(is_X) {
BALL_X +=10;
}else {
BALL_X -=10;
}
if(BALL_X>440){
is_X=false;
}
if(BALL_X<10) {
is_X=true;
}
if(BALL_Y<0) {
is_Y =true;
}
if(is_Y) {
BALL_Y+=10;
}else {
BALL_Y-=10;
}
if(BALL_Y==TABLE_Y-10&&BALL_X>TABLE_X&&BALL_X
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;
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;
//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;
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;
}
}
