這篇文章主要為大家詳細(xì)介紹了java實(shí)現(xiàn)猜數(shù)游戲代碼，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了java實(shí)現(xiàn)猜數(shù)游戲的具體代碼，供大家參考，具體內(nèi)容如下

有開(kāi)始界面，可以設(shè)置范圍，設(shè)置猜的次數(shù)

代碼如下：

public static void main(String[] args) {
 Random rand = new Random();
 Scanner sc = new Scanner(System.in);
 System.out.println("----------猜數(shù)游戲----------");
 System.out.println("  1.開(kāi)始游戲\n  2.游戲設(shè)置\n  3.退出游戲");
 System.out.println("請(qǐng)輸入：");
 int[] arr = new int[3];
 for (int i = 1; i < arr.length; i++) {
  if (i < 4) {
  arr[i] = sc.nextInt();
  }
  break;
 }
 int a = 0;
 //開(kāi)始界面
 for (int i = 1; i < arr.length; i++) {
  if (arr[i] == 1) {
  System.out.println("開(kāi)始游戲");
  a = 1;
  break;
  } else if (arr[i] == 2) {
  System.out.println("游戲設(shè)置");
  a = 2;
  break;
  } else if (arr[i] == 3) {
  System.out.println("退出游戲");
  a = 3;
  break;
  } else System.out.println("錯(cuò)誤輸入");
 }
 //設(shè)置界面
 int max = 100;
 int min = 0;
 int cishu = 5;
 if (a == 2) {
  System.out.println("設(shè)置范圍");
  System.out.println("最小值");
  min = sc.nextInt();
  System.out.println("最大值");
  max = sc.nextInt();
  System.out.println("設(shè)置猜的次數(shù)");
  cishu = sc.nextInt();
  //int randNum = rand.nextInt(max - min + 1) + min;
  System.out.println("設(shè)置范圍\n最小值為：" + min + "\n最大值為：" + max + "\n猜的次數(shù)為：" + cishu);
  a = 6;
 }
 //設(shè)置后回到開(kāi)始界面
 if (a==6){
  System.out.println("----------猜數(shù)游戲----------");
  System.out.println("  1.開(kāi)始游戲\n  2.游戲設(shè)置\n  3.退出游戲");
  System.out.println("請(qǐng)輸入：");
  for (int i = 1; i < arr.length; i++) {
  if (i < 4) {
   arr[i] = sc.nextInt();
  }
  break;
  }
  //開(kāi)始界面
  for (int i = 1; i < arr.length; i++) {
  if (arr[i] == 1) {
   System.out.println("開(kāi)始游戲");
   a = 1;
   break;
  } else if (arr[i] == 2) {
   System.out.println("游戲設(shè)置");
   a = 2;
   break;
  } else if (arr[i] == 3) {
   System.out.println("退出游戲");
   a = 3;
   break;
  } else System.out.println("錯(cuò)誤輸入");
  }
 }
 //游戲界面
 if (a == 1) {
  int randNum = rand.nextInt(max - min + 1) + min;
  System.out.println("我想了一個(gè)" + min + "到" + max + "的數(shù)，請(qǐng)你來(lái)猜：\n你有" + cishu + "次機(jī)會(huì)");
  int i = 1;
  for (; i <= cishu; ++i) {
  System.out.println("第" + i + "次：");
  int guess = sc.nextInt();
  if (i < cishu) {
   if (randNum >= guess) {
   if (randNum <= guess) {
    System.out.println("恭喜你猜對(duì)了！\n" + "該值是：" + randNum);
    break;
   } else System.out.println("你猜小了！");
   } else System.out.println("你猜大了！");
  } else System.out.println("你猜錯(cuò)了！\n該值是：" + randNum);
  }
 }
}
