Question

Wap,take 2 list from user. Both to be of the same length. Print the sum of list 1 and 2 in 3rd list. WAP

Answer 1

Answer:

//we will take the size of the list as 5..

import java.util.*;

public class Main

{

public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);

 ArrayList<Integer> list = new ArrayList<Integer>();

 ArrayList<Integer> list1 = new ArrayList<Integer>();

 ArrayList<Integer> total = new ArrayList<Integer>();

 int sum = 0 , sum1 = 0 , sum2 = 0;

     //loop to create first list

     for(int i = 0; i < 5; i++){

         System.out.print("Enter number " + (i+1) + " in the first list:");

         int x = sc.nextInt();

         list.add(x);

     }

     System.out.println("LIST 1 \n" + list);

     //loop for second list

     for(int i = 0; i < 5; i++){

         System.out.print("Enter number " + (i+1) + " in the second list:");

         int x = sc.nextInt();

         list1.add(x);

     }

     System.out.println("LIST 2 \n" + list1);

     //creating loops for finding the sum

     for(int i = 0; i < list.size(); i++){

         sum = sum + list.get(i);

     }

     for(int i = 0; i < list1.size(); i++){

         sum1 = sum1 + list1.get(i);

     }

     sum2 = sum + sum1;

     total.add(sum2); //adding the total sum to the third list

     System.out.println("The sum of both the lists is : " + sum2);

}

}
