Reversing numbers with leading zeros

Question

I want to write a program that reverses a number (without converting it to a string). I have my code working for all numbers except numbers with leading zeros, for example: 500 and numbers like that. It simply gives me 5 when I want 005 .

Here is my code

System.out.println("Enter a number with at most 10 digits:");
            long inputNumber = myKeyboard.nextLong();
            long tempInputNumber = inputNumber;
            long reversedNumber = 0;
            int digits = 0;
            int rightMostDigit;

            while(tempInputNumber != 0) {
                rightMostDigit = (int)tempInputNumber % 10;
                reversedNumber = (reversedNumber*10)+rightMostDigit;
                tempInputNumber = tempInputNumber / 10;
                digits++;
            }

如果您将每个数字作为一个数字存储在数组中，就像它们用于单热编码一样怎么办？
