Return first digit of an integer

Question

How in Java do you return the first digit of an integer.?

i.e.

345

Returns an int of 3.

Answer 1

public static void firstDigit(int number){      
    while(number != 0){
        if (number < 10){
            System.out.println("The first digit is " + number);
        }
            number = number/10;

        }
    }

When you call it, you can use Maths.abs in order for it to work for negative number:

firstDigit(Math.abs(9584578)); 

This returns 9
