Question

我一直试图让最后的if语句执行，但我没有成功，任何输入都会有帮助

import java.util.Scanner; // Imports the Scanner class for keyboard input.
import java.util.Random; // Imports the Random class to generate a random number.

public class GuessingGameEC {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Random ran = new Random(); 
        int randomNum = ran.nextInt(501); 
        int Guess = 0; 
        Scanner keyboard = new Scanner(System.in); 

        for (int numOfTries = 0; numOfTries <10; numOfTries++) {
        {
            System.out.println(" " );
            System.out.println("Guess what number I'm thinking of between 0 and 500.");
            Guess = keyboard.nextInt();


            if (Guess == randomNum) {
            System.out.println("You guessed the correct number, and it only took you " + numOfTries + " tries." );
            break;


            }

            else if (Guess < randomNum && Guess < 500 && Guess >= 0 && numOfTries != 10) {
            System.out.println("Your guess is too low, please try again!" );


            }

            else if (Guess > randomNum && Guess <= 500 && numOfTries != 10) {
            System.out.println("Your guess is too high, please try again!" );
            }

            else if (Guess > 500 || Guess < 0 ) {
                System.out.println("Please pick a number between 0 and 500!" );
            }


            else if (numOfTries == 10) {

                System.out.println(" " );
                System.out.println("Sorry, you're out of attempts. The correct number was " + randomNum +"!" );

            }
        }

      }

}
}

Answer 1

当for＆gt; = 10时，您的numOfTries循环条件会终止。您应该将最后一段代码放在for循环之外。

Answer 2

当您的for循环从0变为9时，numOfTries == 10的情况永远不会发生。

我会更改您的代码，以便您在成功时返回

if (Guess == randomNum) {
     System.out.println("You guessed the correct number, and it only took you " + numOfTries + " tries." );
        return;
}

然后在循环结束后，您可以无条件地打印失败的

在for循环结束时打印语句时遇到问题
