私の方法は、私がしたいと思ったものに従っていない理由は分かりません

Question

宝くじの回答を格納するランダムに生成された配列とユーザーの入力を比較する宝くじゲームを作ろうとしています（100％答えは時々余分な答えを拾うでしょう。例えば、Total Counterが壊れていますか？）しかし、私の検証方法は間違っていますし、これを修正する方法は不明です。

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

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; 
      } 
     } 
     return totalCorrect; 
    } 
}//End of Public Class TestingClass 

Answer 1

input = userInput.nextInt(); 

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

あなたはここで何かが欠けています。あなたはあなたの入力を検証し、それが有効であれば推測配列にコピーするべきです。

input = userInput.nextInt(); 

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