不确定为什么我的方法没有遵循我想要的方法[关闭]

Question

尝试制作一种将用户输入与存储彩票答案的随机生成数组进行比较的彩票游戏（无法正常运行100％不能确定为什么有时它无法获取答案，有时还会获得额外的答案。例如，总计数器已损坏？）。 但是，我的验证方法不正确，我不确定如何解决此问题？

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

public class TestingClassDemo {
    public static void main(String[] args) {

        int input; //Holds keyboard input
        final int TOTAL_ANSWERS = 10; //Number of answers
        int[] guesses = new int[TOTAL_ANSWERS]; //Array to hold answers

        //Creates a Scanner object for keyboard input
        Scanner userInput = new Scanner(System.in);

        //Gets the users Input
        System.out.println("Welcome to the Lottery!");

        for(int i = 0; i < guesses.length; i++)
        {
            System.out.print("Enter digit " + (i+1) + ": ");
            input = userInput.nextInt();

            while(!validate(guesses[i]))
            {
                System.out.println("Invalid input. Please enter a digit between 1-9");
                System.out.print("Enter digit " + (i+1) + ": ");
                input = userInput.nextInt();
            }
        }

        //Creates a Lottery Object
        TestingClass myLottery = new TestingClass(guesses);


        System.out.print("\nCorrect Numbers: " + (myLottery.totalCorrect()));

    }//End of Main Method
    public static boolean validate(int a)
    {
        boolean status;

        if( a == 1 || a == 2 || a == 3 || a == 4 || a == 5 || a == 6 || a == 7 || a == 8 || a == 9)
            status = true;
        else 
            status = false;
        return status;

    }
}//End of TestingClassDemo

其他类

public class TestingClass {

    private int[] lotteryNumbers = new int[10];

    for(int i = 0; i < lotteryNumbers.length; i++)
    {
        lotteryNumbers[i] = (int) (Math.random()*10);
        System.out.print(lotteryNumbers[i]+ " ");
    }
    }//End of LOOP

    //Creates a Private Array for lotteryNumbers the user Guesses
    private int[] lotteryGuesses = new int[10];

    //Creates a Private int totalCorrect whether correct guesses are stored
    private int totalCorrect = 0;

    //Appends lotteryGuesses to lotteryNumbers for comparison
    public TestingClass(int[] lotteryNumbers)
    {
        lotteryGuesses = lotteryNumbers;
    }

    /** Compares whether the uses LotteryGuess are correct
     and if they are increases total Correct
     */
    public int totalCorrect()
    {
        for( int x = 0; x < lotteryNumbers.length; x++)
        {
            if (lotteryGuesses[x] == lotteryNumbers[x])
            {
                totalCorrect += 1;
            }
        }

Answer 1

input = userInput.nextInt();

while(!validate(guesses[i]))
{
}

您在这里错过了一些东西。 您应该验证您的输入，并在输入有效后将其复制到guesss数组中。

input = userInput.nextInt();

while(!validate(input))
{ 
    ...  
}
guesses[i] = input;
