跟踪并打印使用 while 循环的次数

Question

我正在写一个关于 jgrasp 的小游戏。游戏提示用户猜测 1 到 50 之间的数字。然后，while 循环检查“if”语句，让他们知道他们猜到“高”还是“低”，并提示他们再次猜测。我不知道如何跟踪用户的猜测次数。有小费吗？？我是初学程序员，谢谢大家的帮助。

import java.util.Scanner;

public class Harrison6c {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        System.out.println("Welcome to the land of Hyrule!");
        System.out.println("The land here is extremley dangerous");
        System.out.println("Looks like you could use a sword");
        System.out.println();
        System.out.println("I'll tell you what lets play a game");
        System.out.println("I have a number between 1 and 50");
        System.out.println("Can you guess what it is?");
        System.out.println("If you guess the number correctly");
        System.out.println("I will give you something pretty cool!");
        System.out.println();

        int rand = (int)(Math.random() * (51 - 1)) + 1;

        int guessInt;
        guessInt = 0;

        while (guessInt != rand) {
            System.out.print("Enter your guess: ");
            guessInt = input.nextInt();
            guessInt++;

            if (guessInt > rand) {
                System.out.println("Guess lower");
                System.out.println();
            }
            if (guessInt < rand) {
                System.out.println("Guess higher");
                System.out.println();
            }
        }

        System.out.println("You got It!");
        System.out.println("As promised here is your reward");
        System.out.println("You've recieved the Kokiri Sword!");
        System.out.println("Remember this land is very dangerous");
        System.out.println("That sword you now yield shall protect you!");

        System.out.println("You took" + guessInt++ + "guessess");
    }
}

这是我的输出

 ----jGRASP exec: java Harrison6c
Welcome to the land of Hyrule!
The land here is extremley dangerous
Looks like you could use a sword

I'll tell you what lets play a game
I have a number between 1 and 50
Can you guess what it is?
If you guess the number correctly
I will give you something pretty cool!

Enter your guess: 50
Guess lower

Enter your guess: 30
Guess lower

Enter your guess: 20
Guess higher

Enter your guess: 25
Guess higher

Enter your guess: 24
Guess higher

Enter your guess: 27
Guess higher

Enter your guess: 28
Guess higher

Enter your guess: 29
You got It!
As promised here is your reward
You've recieved the Kokiri Sword!
Remember this land is very dangerous
That sword you now yield shall protect you!
You took30guessess

 ----jGRASP: operation complete.

Answer 1

使用另一个变量来增加猜测次数 -

int guessInt = 0;
int guesses = 0; // this would track the count of guesses

while( guessInt != rand) {
  System.out.print( "Enter your guess: " );
  guessInt = input.nextInt();
  guesses++;

  if(guessInt > rand) {
    System.out.println("Guess lower");
    System.out.println();
  }
  if(guessInt < rand) {
   System.out.println("Guess higher");
   System.out.println();
  }
}

....
System.out.println("You took" + guesses + "guessess");
...

注意 - 您可以通过避免使用这么多 S.outs 并有效地使用 \n 来清理您的代码。

Answer 2

将Int 替换为guessInt

System.out.println("You took"+guessInt++ +"guessess");
