Return second last digit of given number

In this topic, we will learn to get the second last digit of a number with the help of examples.
There can be several ways to get second last digit; here we are discussing some solutions.

Using modulo operator

Here, we are using modulo and divide operators to find the second last digit. The modulo operator gives remainder of a number while divide operator gives quotient as a result.

public class Main{
    public static void main(String[] args){
        int a = 120025;
        int secondLastDigit = (a % 100) / 10;
        System.out.println(secondLastDigit);
        secondLastDigit = (a / 10) % 10;
        System.out.println(secondLastDigit);
    }
}

Output

Using String’s chartAt() method

There is another example in which we can convert the number into a string and then using charAt() method we get second last value after that result convert back to number using Character class.

public class Main{
    public static void main(String[] args){
        int a = 120025;
        String number = Integer.toString(a);
        System.out.println(number);
        int secondLastDigit = Character.getNumericValue((number.charAt(number.length()-2)));
        System.out.println(secondLastDigit);
    }
}

Output

That’s all about how to return second last digit of given number.
