java - 做猜谜游戏的 while 循环

Question

我正在编写一个简单的java猜谜游戏，该游戏应该随机选择1到100之间的一个数字，然后在你选择正确的数字后，它会询问你是否想再玩一次。我知道我应该能够使用 Do while 循环来询问用户是否想再次玩，但每次我尝试都无法使其工作。这是我的功能齐全的程序，没有 do while 循环。如果有人可以帮助我提示用户是否想再次玩，我将非常感激。我对编程还很陌生。如果缩进不是 100% 正确，我也深表歉意。

import java.util.Scanner;
import java.util.Random;
public class GuessingGame
{
   public static void main (String [] args)
   {


  //Variables
  Random randomNumber = new Random();
  Scanner kbd = new Scanner(System.in);
  int computerValue = randomNumber.nextInt(100);
  int numberOfTries = 0;
  int success = 0;
  int guess = 0;


  //Logic and While Loop



   while (success ==0)
     {
        System.out.println("please enter an integer betwen 1 and 100 inclusive: ");
        guess = kbd.nextInt();
        numberOfTries++;

           if (guess < 1 || guess > 100){
              System.out.println("Invalid input");
           }

           else if (guess == computerValue){
              success++;
              System.out.println("Congratulations you won! Your numbers of tries was: " + numberOfTries + " and the number was: " + computerValue);

           }
           else if (guess < computerValue){
              System.out.println("Your guess is too low!");
           }
           else if (guess > computerValue){
              System.out.println("Your guess is too high!");
    }
    }



   }
}

试试这个:

while(true) {
    computerValue = randomNumber.nextInt(100);
    numberOfTries = 0;
    while (true) {
        System.out.println("please enter an integer betwen 1 and 100 inclusive: ");
        guess = kbd.nextInt();
        numberOfTries++;

        if (guess < 1 || guess > 100) System.out.println("Invalid input");
        else if (guess == computerValue) {
            System.out.println("Congratulations you won! Your numbers of tries was: " + numberOfTries + " and the number was: " + computerValue);
            // leave the first loop
            break;
        }
        else if (guess < computerValue) System.out.println("Your guess is too low!");
        else if (guess > computerValue) System.out.println("Your guess is too high!");
    }

    System.out.println("Do you want to play again? (1:Yes/2:No)");
    // if input is not yes leave second loop
    if(kbd.nextInt() != 1) break;
}
