java - 带随机数生成器的 HiLo 游戏

Question

我有一个关于这款 HiLo 游戏的快速问题。当我去测试它时，一切正常，除非我希望它显示他们猜测了多少次尝试。我想说的是，它不计算最初的猜测，而是计算其后的猜测，因此它显示的猜测比实际的猜测少一个。这是我的代码。

编辑:我还有另一个简单的问题。如果超出 0 到 10 的范围，我希望程序不要计算猜测值。我将如何执行此操作，因为当我运行程序时，它将猜测值算作我的尝试之一。

import java.util.Random;     // Random number generator class
import java.util.Scanner;    // reads user inputs

public class HiLo
{
	public static void main (String[] args)
	{
		//declare variables
		final int MAX = 10;
		int answer, guess;
		int numberOfTries = 0 ;
		String again;

		Scanner Keyboard = new Scanner(System.in);

		do

		{
			System.out.print (" I'm thinking of a number between 0 and "
			+ MAX + ". Guess what it is: ");
			guess = Keyboard.nextInt();
			//guess
			Random generator = new Random(); //Random  number generator. 0 to 10.
			answer = generator.nextInt(MAX) +1;

			if (guess > 10)//if guess is bigger than 10 then error message
			{
			System.out.println ("ERROR – Your guess is out of the range 0 to 10.");
			}
			if (guess < 0)//if guess is smaller than 0 then error message
			{
		    System.out.println ("ERROR – Your guess is out of the range 0 to 10.");
			}

			while (guess != answer )//If guess is not the answer
			{

			if (guess > answer )//If guess is more than the answer
			{
			System.out.println ("You guessed too high! \nTry again:");
			guess = Keyboard.nextInt();
			}

			if (guess < answer )//If guess is less than the answer
			{
			System.out.println ("Too Low! \nTry again:");
			guess = Keyboard.nextInt();
			}

			numberOfTries=numberOfTries+1;

			}//end of the loop

			// display result
			if ( guess == answer)
			{
			numberOfTries += 1;
			System.out.println ("YOU WIN!");
			System.out.println("It took you " + numberOfTries + " tries!") ;
			System.out.println();
			System.out.print( "Do you want to play again(Y/N)?");
			}


			Keyboard.nextLine(); // skip over enter key
			again = Keyboard.nextLine();

			numberOfTries=0;



		}while (again.equalsIgnoreCase ("Y") );



	} // end of class

} //end of main

谢谢!

你应该将 numberOfTries += 1 放在 if (猜测==答案) 中，这样它也会计算正确答案

if ( guess == answer)
        {
        numberOfTries += 1;   // <--- This adds the final guess
        System.out.println ("YOU WIN!");
        System.out.println("It took you " + numberOfTries + " tries!") ;
        System.out.println();
        System.out.print( "Do you want to play again(Y/N)?");
        }
