java - 我该如何添加 "You got it right in ... guesses!"

Question

我需要添加“你猜对了……猜对了!”但我不太确定怎么做。有人可以向我解释一下如何在java中做到这一点吗？

我希望它在最后显示一个 println ，说明用户尝试了多少次才能获得正确的数字。

import java.util.*;

public class prog210c
{
  public static void main()
  {
      Scanner sc = new Scanner(System.in);
      Random rn = new Random();

      int randomNum = rn.nextInt(90) + 10;

      System.out.println("I am thinking of a number between 1 and 100");

      while (true) {
          System.out.print("What do you think it is? ");
          int guess = sc.nextInt();

          if(guess < randomNum)
          {
              System.out.println("Higher--Try Again");
          }

          else if(guess > randomNum)
          {
              System.out.println("Lower--Try Again");
          }

          else if(guess == randomNum)
          {
              System.out.println("Correct!");
              break;
          }

          else
          {
              System.out.println("Enter a number between 1 and 100");
          }
        }

      //System.out.println("You got it right in " + + " guesses");

  } //end main
} //end class

只需创建一些 int 变量来存储您的尝试次数，并在每次读取猜测时递增它。

int attempts = 0;

System.out.println("I am thinking of a number between 1 and 100");

while (true) {
    System.out.print("What do you think it is? ");
    int guess = sc.nextInt();
    attempts++;

    /**
     * The rest of your loop code here.
     */
}

System.out.println("You got it right in " + attempts + " guesses");
