Question

write a program to initialise 20 integers in an array[] print the array horizontally with one is space between each number at the end print sum of all even integers and sum of odd integers from the array​

Answer 1

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);

 int[] arr = new int[20];

 int evenSum = 0 , oddSum = 0;

 int n = arr.length;

 System.out.println("Enter all 20 numbers in the array");

     for(int i = 0; i < n; i++){

         arr[i] = sc.nextInt();

             if(arr[i]%2 == 0){

                 evenSum += arr[i];

             }

             else if(arr[i]%2 == 1){

                 oddSum += arr[i];

             }

     }

     for(int i = 0; i < n; i++){

         System.out.print(arr[i] + " ");

     }

     System.out.println("\nthe sum of all even numbers in the array is " + evenSum);

     System.out.println("the sum of all odd numbers in the array is " + oddSum);

}

}
