Java HiLo游戏-无法生成新的猜测

Question

抱歉，我知道这个游戏还有其他帖子，但是我的问题很具体。 我刚开始学习Java，并一起玩了这款HiLo游戏，但我正努力降低2件事-

1）如果用户想再次玩，我如何获得它以产生新的选择？ 现在，如果您再次玩游戏，您将获得相同的选择权2）如果用户选择中止游戏，则不会产生消息

求求您，我是我的新手，并且容易受Java的侵扰！

        //randomly pick a number between 1-100
        Random rand = new Random();
        int pick = rand.nextInt(100) + 1;
        int count = 0;
        boolean play = true;

        //prompt user to guess

            }


            if (guess == pick)
            {

                System.out.println("Want to play again?");

                else
                    play = false;
            }
        }

        if (play = false || guess == 0) 
        {
            System.out.println("Bummer. See you next time!");
        }

     }
}

Answer 1

两件事

int pick = rand.nextInt(100) + 1;
// ...

//on each guess, say if too low or too high
while (play = true)
{   

一个=是分配，两个==是相等。 所以while (play == true) （冗长） 或 while (play) 。 然后将pick移入循环。

// int pick = rand.nextInt(100) + 1;
// ...
while (play) {   
    int pick = rand.nextInt(100) + 1;

那应该解决两个问题。

Answer 2

只是分配一个新的值pick你，如果条件变量，你测试的平等guess和pick

if (guess == pick)
{   
  System.out.println("You got it! It only took you " + count + " guesses.");
  System.out.println("Want to play again?");
  System.out.println("* Guess a number between 1-100:   *");
  System.out.println("* (enter \"0\" to end at any time)  *");
  guess = scan.nextInt();

  pick = rand.nextInt(100) + 1; // new value

  if (guess != 0)
    play = true;
  else
    play = false;
}
