Question

我正在尝试创建一个随机数游戏，其中用户给出较低和较高的数字，程序询问他/她想要多少猜测，然后继续猜测数字。

    Scanner s = new Scanner(System.in);
    System.out.print("Enter a low number: ");
    int min = s.nextInt();
    System.out.print("Enter a high number: ");
    int max = s.nextInt();
    Random rand = new Random();
    int value = rand.nextInt((max - min) + 1) + min;
    System.out.print("The Random Number is " + value);

这会在给定的值之间找到一个随机值，我认为我需要一个for循环来猜测，但是找出如何做到这一点变得困难任何想法？

Answer 1

在当前代码之前添加以下行：

Scanner s = new Scanner(System.in);
System.out.print("Enter the number of guesses: ");
int count = s.nextInt();

然后，将代码置于如下循环中：

for(int i=0; i<count; i++){
  System.out.print("Enter a low number: ");
  int min = s.nextInt();
  System.out.print("Enter a high number: ");
  int max = s.nextInt();
  Random rand = new Random();
  int value = rand.nextInt((max - min) + 1) + min;
  System.out.print("The Random Number is " + value);
}

You can do it in this way :-

Scanner s = new Scanner(System.in);
            System.out.print("Enter a low number: ");
            int min = s.nextInt();
            System.out.print("Enter a high number: ");
            int max = s.nextInt();
            Random rand = new Random();
            System.out.println("Enter no of guesses : ");
            int noOfGuesses = s.nextInt();

            for(int i=0; i < noOfGuesses; i++){
                int value = rand.nextInt((max - min) + 1) + min;
                System.out.print("\nThe Random Number is " + value);
            }

Here is the output :- Enter a low number: 5
Enter a high number: 50
Enter no of guesses : 
5

The Random Number is 45
The Random Number is 42
The Random Number is 40
The Random Number is 9
The Random Number is 12
