Java--制作乱字游戏
2024-05-15 21:35:07
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.*;

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" };

在Menu中写入代码如下：
1 package game;
2

45 c.weighty = 0.1;
46 c.anchor = c.CENTER;
47 add(name, c);

49 c.gridx = 0;
50 c.gridy = 1;
51 c.fill = c.HORIZONTAL;
52 add(option1, c);

69 GameWindow obj = new GameWindow();
70 obj.stratGame();
71 } else if (e.getSource() == option2) {
72 JOptionPane.showMessageDialog(this, "1.You can"
73 + " guess the word by clicking the character from the virtual keypad.\n"
74 + "2.You can select a maximum color, and the correct one will be highlighted with green color.",
75 "Instructions ", JOptionPane.INFORMATION_MESSAGE);
76 ;
77 } else if (e.getSource() == option3) {
78 System.exit(0);
79
80 }
81 }
82 }View Code
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。
