Question

import java.util.Random;
import java.util.Scanner;

public class GuessingGame {

  public static void main (String [] args) {

    Random rand = new Random ();
    int numberToGuess = rand.nextInt (100);
    int numberOfTries = 0;
    Scanner input = new Scanner (System.in);
    int guess;

    boolean win = false;

    while (win == false); {

      System.out.println("Guess a number between 1 and 100:");
      guess = input.nextInt (); 
      numberOfTries++;

      if (guess == numberToGuess) {
        win = true;
      }

      else if (guess > numberToGuess) {
        System.out.println ("You guessed too low mate!");
      }

      else if (guess > numberToGuess) {
        System.out.println ("You guessed too high mate!") ;

        System.out.println("You win!!");
        System.out.println("The random number WAS!" + numberToGuess);
        System.out.println("It took you a wopping" + numberOfTries + "TRIES!");

      }
    }
  }
} 

这是我的代码，当我尝试运行它时，它基本上卡在这里:

欢迎来到 java 博士。工作目录是 U:\Downloads运行猜谜游戏

如何解决这个问题，以便我可以正常运行程序而不会出现上述错误？

Answer 1

我发现两个错误。

while (win == false); {

应该是

while (win == false) {

(或 while(!win) {)，因为分号创建一个空循环体。并且

  else if (guess > numberToGuess) {
    System.out.println ("You guessed too low mate!");
  }

应该是

  else if (guess < numberToGuess) {
    System.out.println ("You guessed too low mate!");
  }

或者你有两个更高的测试(这种方式是有意义的)。
