Java的帶GUI界面猜數(shù)字游戲的實現(xiàn)示例

先導(dǎo)包

import java.util.*;
import javax.swing.*;

再寫主方法

public static void main(String[] args) {
}

新聲明一個Scanner和隨機數(shù)

public static void main(String[] args) {
	Scanner in = new Scanner(System.in);
	Random r = new Random();
}

讓UIManager爬取系統(tǒng)窗口樣式

try {
  UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
  e.printStackTrace();
}

新建一個int類型的變量存儲隨機數(shù)

int secret = r.nextInt(32) + 1;

寫入主程序

JOptionPane.showMessageDialog(null, "電腦隨機生成了一個1~32之間的數(shù)，請猜出這個數(shù)", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);
String number2 = (String) JOptionPane.showInputDialog(null, "請輸入想猜的數(shù)：", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE, null, null, "");
int number = Integer.parseInt(number2);
while (number != secret) {
  if (number > secret) {
    JOptionPane.showMessageDialog(null, "你猜的數(shù)大了，請繼續(xù)猜", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);
    number2 = (String) JOptionPane.showInputDialog(null, "請輸入想猜的數(shù)：", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE, null, null, "");
    number = Integer.parseInt(number2);
  } else {
    JOptionPane.showMessageDialog(null, "你猜的數(shù)小了，請繼續(xù)猜", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);
    number2 = (String) JOptionPane.showInputDialog(null, "請輸入想猜的數(shù)：", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE, null, null, "");
    number = Integer.parseInt(number2);
  }
}
JOptionPane.showMessageDialog(null, "恭喜你，你猜對了，電腦生成的隨機數(shù)是" + secret, "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);

全部代碼

package com.demo05;

import java.util.*;
import javax.swing.*;

public class MathDemo03 {
  public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    Random r = new Random();
    int secret = r.nextInt(32) + 1;
    try {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    } catch (Exception e) {
      e.printStackTrace();
    }
    JOptionPane.showMessageDialog(null, "電腦隨機生成了一個1~32之間的數(shù)，請猜出這個數(shù)", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);
    String number2 = (String) JOptionPane.showInputDialog(null, "請輸入想猜的數(shù)：", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE, null, null, "");
    int number = Integer.parseInt(number2);
    while (number != secret) {
      if (number > secret) {
        JOptionPane.showMessageDialog(null, "你猜的數(shù)大了，請繼續(xù)猜", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);
        number2 = (String) JOptionPane.showInputDialog(null, "請輸入想猜的數(shù)：", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE, null, null, "");
        number = Integer.parseInt(number2);
      } else {
        JOptionPane.showMessageDialog(null, "你猜的數(shù)小了，請繼續(xù)猜", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);
        number2 = (String) JOptionPane.showInputDialog(null, "請輸入想猜的數(shù)：", "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE, null, null, "");
        number = Integer.parseInt(number2);
      }
    }
    JOptionPane.showMessageDialog(null, "恭喜你，你猜對了，電腦生成的隨機數(shù)是" + secret, "猜數(shù)字游戲", JOptionPane.PLAIN_MESSAGE);
  }
}
