Sum of large numbers in java

Question

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

public class LargeSum {

    public static void main(String[] args) {
        Scanner inp=new Scanner(System.in);
        int limit=inp.nextInt();
        BigInteger[] arr=new BigInteger[limit];
        for (int i=0; i<limit; i++) 
            arr[i]=new BigInteger(inp.nextLine());  //runtime error
        BigInteger sum=new BigInteger(String.valueOf(arr[0]));
        for (int i=1; i<limit;i++) 
            sum=sum.add(arr[i]);
    }

}

I've written a code to find the sum of user given amount of large numbers in java using BigInteger class, but I reached a runtime error "java.lang.NumberFormatException: Zero length BigInteger". How can I fix this issue? Sample input:

Answer 1

Advance to the next line first.

int limit=inp.nextInt();
inp.nextLine();

Or, use the Integer#parseInt method.

int limit=Integer.parseInt(inp.nextLine());

Output
