Write a Java program to compute and print sum of two given integers (more than or equal to zero). If given integers or the sum have more than 80 digits, print "overflow"

 import java.*;
import java.math.BigInteger;
import java.util.Scanner;
 
public class Main {
    public static void main(String args[]) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Input two integers:");
        String s1 = new String();
		String s2 = new String();
        s1 = sc.nextLine();
        s2 = sc.nextLine();
        BigInteger b1 = new BigInteger(s1);
        BigInteger b2 = new BigInteger(s2);
        BigInteger result = new BigInteger("0");
        result = result.add(b1);
        result = result.add(b2);
        String s3 = ""+result;
		System.out.println("\nSum of the said two integers:");
        if(s1.length()>80 || s2.length()>80 || s3.length()>80)
            System.out.println("Overflow");
        else
            System.out.println(result);
          }    
}

Sample Output:

Input two integers:
25
46

Sum of the said two integers:
71
