首先创建一个Java project，在其中创建如下类：

在GameWindow中写入代码如下：

  1 package game;
  2 
  3 import java.awt.BorderLayout;
  4 import java.awt.Color;
  5 import java.awt.FlowLayout;
  6 import java.awt.Font;
  7 import java.awt.GridBagConstraints;
  8 import java.awt.GridBagLayout;
  9 import java.awt.event.ActionEvent;
 10 import java.awt.event.ActionListener;
 11 import java.util.Random;
 12 
 13 import javax.swing.*;
 14 
 15 public class GameWindow extends JFrame implements ActionListener {// 窗口充当监听器 {
 16     JButton a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z;
 17     JLabel lblword, lblmessage;
 18     JPanel keypad, key1, key2, key3, screen, notify;
 19     int len, count, chance, flag, rnd;
 20     Random rd;
 21     String word[] = { "JAPAN", "QATAR", "SYRIA", "MONGOLIA", "BAHARAIN", "INDIA", "PAKISTAN", "AUSTRALIA", "AFGHNISTAN",
 22             "CHINA" };

 24     StringBuffer blanks;

77         } else if (e.getSource() == option3) {
78             System.exit(0);
79 
80         }
81     }
82 }

另外，添加了2个异常的处理：

在MenuInputException中写入代码如下：

1 package game;
2 
3 public class MenuInputException extends RuntimeException {
4     MenuInputException() {
5         System.out.println("Please provide a valid input(1-3)");
6     }
7 }

分析：该段代码为在命令行界面运行时，出现选择超过3 ，则报出异常，但是在命令行界面不会出现。

在WrongInputException中写入代码如下：

1 package game;
2 
3 public class WrongInputException extends RuntimeException {
4     WrongInputException(){
5         System.out.println("Please provide a single character only..!!");
6     }
7 }

分析：该段代码也是在命令行运行时可能出现单次输入的字母不为一个，则报出异常。同样ui界面不会出现。

运行结果如下：

出现如下窗口：窗口中有三个选项：play Game,View Introduction,Exit

点击Play Game 出现下图，表示开始玩游戏

点击View Intorduction界面弹出消息对话框，提示游戏规则：

点击Exit,就直接退出。
