我本来想做一个石头剪刀布的游戏哩，有两个类：Main.java和Game.java。其中Main.java是启动类。
Game.java的代码如下：
package surface;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.Random;
public class Game extends JFrame implements ActionListener {
JMenuBar mb;
JComboBox<String> box;
static String[] way = new String[] {"石头","剪刀","布"};
Label yourLabel;
int randomNum;
int count = 1;
Object[][] table = new Object[3][3];
/**
* 游戏
*/
public Game() {
this.launch();
this.addCompoments();
}
/**
*
*/
private void getHelp() {
String str = "这个游戏的灵感来自于我们耳熟能详的游戏——石头剪刀布。\n"
+ "这个游戏采用了三局两胜制，下面有本次打开日志，可以自行查看。\n"
+ "注：如果平局，算电脑获胜。";
JOptionPane.showMessageDialog(this, str);
}
/**
* 添加组件
*/
private void addCompoments() {
//获取容器
Container con = getContentPane();
con.setLayout(null);
//菜单栏
mb = new JMenuBar();
JMenu m1 = new JMenu("文件");
JMenuItem mi1 = new JMenuItem("确定(O)");
mi1.addActionListener(this);
m1.add(mi1);
mb.add(m1);
JMenu m2 = new JMenu("帮助");
JMenuItem mi2 = new JMenuItem("游戏操控(K)");
mi2.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
getHelp();
}
});
m2.add(mi2);
mb.add(m2);
this.setJMenuBar(mb);
//题目
JLabel title = new JLabel("<html><center><b>石头剪刀布<b></center></html>");
title.setFont(new Font("微软雅黑",Font.BOLD,25));
title.setBounds(70,10,160,30);
con.add(title);
//标签1
Label myLabel = new Label("请选择你出的拳：");
myLabel.setBounds(0, 50, 100, 30);
con.add(myLabel);
//准备选择框
box = new JComboBox<>();
box.addItem("石头");
box.addItem("剪刀");
box.addItem("布");
box.setBounds(0, 90, getWidth() - 18, 25);
con.add(box);
//标签2
yourLabel = new Label("电脑出了：");
yourLabel.setBounds(0, 125, getWidth(), 30);
con.add(yourLabel);
//按钮“确定”
Button ok = new Button("确定");
ok.setBounds(110, 155, 60, 30);
ok.addActionListener(this);
con.add(ok);
}
/**
* 初始化本身
*/
private void launch() {
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(300,300);
setLocationRelativeTo(null);
setResizable(false);
setTitle("石头剪刀布");
try {
UIManager.setLookAndFeel("javax.swing.plaf.nimbus.NimbusLookAndFeel");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UnsupportedLookAndFeelException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* 检查
*/
private void update(String whoWin) {
table[count-1][count-1] = new Object[] {count-1,whoWin};
count++;
}
/**
* 检查是否结束
*/
private void checkCanOver() {
if (!(count<6)) {
dispose();
JOptionPane.showMessageDialog(null, "本次游戏结束。");
//投票
int myIndex = 0,computerIndex = 0;
String winner;
int style;
for (int i = 0;i < 3;i++) {
String who = table[i][i].toString();
if (who=="computer") {
computerIndex++;
} else if (who=="me") {
myIndex++;
}
}
if (myIndex > computerIndex) {
winner = "电脑";
style = JOptionPane.ERROR_MESSAGE;
} else {
winner = "你";
style = JOptionPane.INFORMATION_MESSAGE;
}
JOptionPane.showMessageDialog(this,
"最终的赢家是："+winner+"！",
winner,
style
);
} else {
return;
}
}
/**
* 点击事件
* @param e
*/
@Override
public void actionPerformed(ActionEvent e) {
if (count < 6) {
Random rand = new Random();
randomNum = rand.nextInt(3);
yourLabel.setText("电脑出了：" + way[randomNum]);
try {
Thread.sleep(2000);
} catch (InterruptedException e1) {
System.err.println("InterruptedException.");
}
StringBuilder sb = new StringBuilder();
sb.append("电脑出的是");
sb.append(way[randomNum]);
sb.append("，你出的是");
sb.append(box.getSelectedItem());
sb.append("。");
JOptionPane.showMessageDialog(getContentPane(), sb.toString());
sb = null;
System.gc();
check();
}
}
/**

*/
private void check() {
//检查
final int myChoice = box.getSelectedIndex() + 1;
final int yourChoice = randomNum + 1;
//判断
if (myChoice==yourChoice) {
JOptionPane.showMessageDialog(this, "平局！（如果平局算作电脑赢）");
update("computer");
count++;
System.out.println(count);
checkCanOver();
return;
}
/*
* 1=石头
* 2=剪刀
* 3=布
*/
switch (myChoice) {
case 1:
System.out.println(1);
if (yourChoice==2) {
youWin();
update("me");
} else {
youLose();
update("computer");
}
count ++;
break;
case 2:
System.out.println(2);
if (yourChoice==3) {
youWin();
update("me");
} else {
youLose();
update("computer");
}
count++;
break;
case 3:
System.out.println(3);
if (yourChoice==1) {
youWin();
update("me");
} else {
youLose();
update("computer");
}
count++;
break;
}
System.out.println(count);
checkCanOver();
}
/**
* 你赢了
*/
private void youWin() {
JOptionPane.showMessageDialog(null,
"在这一轮，你胜利了！",
"胜利",
JOptionPane.INFORMATION_MESSAGE);
}
/**
* 你输了
*/
private void youLose() {
JOptionPane.showMessageDialog(null,
"在这一轮，你失败了！",
"失败",
JOptionPane.ERROR_MESSAGE);
}
}
Main.java的代码如下：
package main;
import surface.Game;
public class Main {
public static void main(String[] args) {
// TODO Auto-generated method stub
new Game().setVisible(true);
}
}
其中Game.count有一些Bug，请修复一下。
