有开始界面,可以设置范围,设置猜的次数

代码如下:

public static void main(String[] args) {
 Random rand = new Random();
 Scanner sc = new Scanner(System.in);
 System.out.println("----------猜数游戏----------");
 System.out.println("  1.开始游戏\n  2.游戏设置\n  3.退出游戏");
 System.out.println("请输入:");
 int[] arr = new int[3];
 for (int i = 1; i < arr.length; i++) {
  if (i < 4) {
  arr[i] = sc.nextInt();
  }
  break;
 }
 int a = 0;
 //开始界面
 for (int i = 1; i < arr.length; i++) {
  if (arr[i] == 1) {
  System.out.println("开始游戏");
  a = 1;
  break;
  } else if (arr[i] == 2) {
  System.out.println("游戏设置");
  a = 2;
  break;
  } else if (arr[i] == 3) {
  System.out.println("退出游戏");
  a = 3;
  break;
  } else System.out.println("错误输入");
 }
 //设置界面
 int max = 100;
 int min = 0;
 int cishu = 5;
 if (a == 2) {
  System.out.println("设置范围");
  System.out.println("最小值");
  min = sc.nextInt();
  System.out.println("最大值");
  max = sc.nextInt();
  System.out.println("设置猜的次数");
  cishu = sc.nextInt();
  //int randNum = rand.nextInt(max - min + 1) + min;
  System.out.println("设置范围\n最小值为:" + min + "\n最大值为:" + max + "\n猜的次数为:" + cishu);
  a = 6;
 }
 //设置后回到开始界面
 if (a==6){
  System.out.println("----------猜数游戏----------");
  System.out.println("  1.开始游戏\n  2.游戏设置\n  3.退出游戏");
  System.out.println("请输入:");
  for (int i = 1; i < arr.length; i++) {
  if (i < 4) {
   arr[i] = sc.nextInt();
  }
  break;
  }
  //开始界面
  for (int i = 1; i < arr.length; i++) {
  if (arr[i] == 1) {
   System.out.println("开始游戏");
   a = 1;
   break;
  } else if (arr[i] == 2) {
   System.out.println("游戏设置");
   a = 2;
   break;
  } else if (arr[i] == 3) {
   System.out.println("退出游戏");
   a = 3;
   break;
  } else System.out.println("错误输入");
  }
 }
 //游戏界面
 if (a == 1) {
  int randNum = rand.nextInt(max - min + 1) + min;
  System.out.println("我想了一个" + min + "到" + max + "的数,请你来猜:\n你有" + cishu + "次机会");
  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("恭喜你猜对了!\n" + "该值是:" + randNum);
    break;
   } else System.out.println("你猜小了!");
   } else System.out.println("你猜大了!");
  } else System.out.println("你猜错了!\n该值是:" + randNum);
  }
 }
}
