这是我迄今为止制定的准则。

import java.util.Scanner;
import java.util.Random;

public class GuessANumber {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        
        System.out.print("Enter a random seed: ");
        int seed = scanner.nextInt();
        Random rnd = new Random (seed);
        
        int rightAnswer = rnd.nextInt(200)+1;
        
        int numAttempts = 0;
        
        System.out.print("Enter a guess between 1 and 200: ");
        int guess = scanner.nextInt();
        numAttempts ++;
        
        while (guess != rightAnswer) {
           if (guess < 1 || guess > 200) {
              System.out.println("Your guess is out of range. Pick a number between 1 and 200.");
           }
           if (guess > rightAnswer) {
              System.out.println("Your guess was too high - try again.");
           }
           else if (guess < rightAnswer) {
              System.out.println("Your guess was too low - try again.");
           }
           System.out.println();
           System.out.print("Enter a guess between 1 and 200: ");
           guess = scanner.nextInt();
           numAttempts ++;
        }
        
        if (guess == rightAnswer) {
           System.out.println("Congratulations!  Your guess was correct!");
           System.out.println();
           System.out.println("I had chosen " + rightAnswer + " as the target number.");
           System.out.println("You guessed it in " + numAttempts + " tries.");
        }
        
        if (numAttempts == 1) {
           System.out.println("That was impossible!");
        }
        else if (numAttempts == 2 || numAttempts == 3) {
           System.out.println("You re pretty lucky!");
        }
        else if (numAttempts >= 4 && numAttempts <= 7) {
           System.out.println("Not bad, not bad...");
        }
        else if (numAttempts == 8) {
           System.out.println("That was not very impressive.");
        }
        else if (numAttempts == 9 || numAttempts == 10) {
           System.out.println("Are you having any fun at all?");
        }
        else if (numAttempts >= 11) {
           System.out.println("Maybe you should play something else.");
        }
        
        scanner.close();

    }
}

这是产出应当做到的:

Enter a random seed: Enter a guess between 1 and 200: Your guess is out of range.  Pick a number between 1 and 200.
Your guess was too low - try again.

Enter a guess between 1 and 200: Your guess was too low - try again.

Enter a guess between 1 and 200: Your guess is out of range.  Pick a number between 1 and 200.
Your guess was too high - try again.

然而,我关于这一试验的法规规定,除此外,还有一线白色空间,如:

Enter a random seed: Enter a guess between 1 and 200: Your guess is out of range. Pick a number between 1 and 200.
Your guess was too low - try again.

Enter a guess between 1 and 200: Your guess was too low - try again.

Enter a guess between 1 and 200: Your guess is out of range. Pick a number between 1 and 200.
Your guess was too high - try again.
