program to find the sum if the elements of an array java code example

Example 1: how to get array input in java

public class TakingInput {

    public static void main(String[] args) {

        Scanner s=new Scanner(System.in);

        System.out.println("enter number of elements");

        int n=s.nextInt();

        int arr[]=new int[n];

        System.out.println("enter elements");

        for(int i=0;i<n;i++){//for reading array
            arr[i]=s.nextInt();

        }

        for(int i: arr){ //for printing array

            System.out.println(i);

        }


    }

}

Example 2: add each element in an array java

import java.util.Arrays;
import java.util.Scanner;
public class SumOfElementsOfAnArray {
   public static void main(String args[]){
      System.out.println("Enter the required size of the array :: ");
      Scanner s = new Scanner(System.in);
      int size = s.nextInt();
      int myArray[] = new int [size];
      int sum = 0;
      System.out.println("Enter the elements of the array one by one ");

      for(int i=0; i<size; i++){
         myArray[i] = s.nextInt();
         sum = sum + myArray[i];
      }
      System.out.println("Elements of the array are: "+Arrays.toString(myArray));
      System.out.println("Sum of the elements of the array ::"+sum);
   }
}
