How to add two numbers of any length in java?

Say for example, in java long size is 64 bit. So the maximum range is -9223372036854775808 to 9223372036854775807. Am i

Answer 1

    import java.math.BigInteger;
    import java.util.Scanner;

    public class BigIntergerSumExample {

        public static void main(String args[]) {

            BigInteger number1;
            BigInteger number2;
            BigInteger sum;
            Scanner sc = new Scanner(System.in);
            System.out.println("Enter the value of number 1");
            number1 = sc.nextBigInteger();
            System.out.println("Enter the value of number 2");
            number2 = sc.nextBigInteger();


            BigInteger a = new BigInteger(""+number1);
            BigInteger b = new BigInteger(""+number2);
            BigInteger result = a.add(b);

            System.out.println("Sum is Two numbers : -> " + result);
        }

    }

**OUTPUT IS** 

Enter the value of number 1
1111111111111111111111111111111111111111111111111
Enter the value of number 2
2222222222222222222222222222222222222222222222222
Sum is Two numbers : -> 
3333333333333333333333333333333333333333333333333

import java.math.BigInteger will let you work with numbers of any size,
