java - 如何从 do while 循环内部检索变量值

Question

我是 Java 初学者，正在为一门类(class)开发 Mastermind 项目。

我有一个问题。我想检索 leftDigit 的值并将其放入数组 guess[4] 中。但我不知道如何在循环之外检索它。

假设当我输入数字 1234 时，我希望它变成 int[]guess = { 1, 2, 3, 4};`

public static void inputNumber(){   

        Scanner input = new Scanner(System.in);
        currentRow++;

        System.out.printf ("Enter 4 numbers for attempt #%d: ", currentRow);

        int count = 10000, leftDigit;
        double tempNum;

        int number = input.nextInt();


        //finding the left digit   
        do{    
            tempNum = (double) number / count ;  
            leftDigit =  (int) (tempNum * 10) ;         
            count /=10;                         
            number = number - ( count * leftDigit);             
        } while (count != 1 );
    }

    int [] guess = new int[4];
    int i = 0;
    //finding the left digit   
    do{    
        tempNum = (double) number / count ;  
        leftDigit =  (int) (tempNum * 10) ;

        guess[i++] = leftDigit;

        count /=10;                         
        number = number - ( count * leftDigit);             
    } while (count != 1 );

    //Use guess as you want it contains the 4 digits you need
