Question

Write a java program that declares 10 element array (of type integers), creates and initializes the array, and perform the sum of elements of the array using for loop.  

public class SumArray {

public static void main (String[], args) {

} // end of main

} // end of SumArray class

Answer 1

import java.util.Scanner;

public class SumArray2 {
    public static void main (String[] args) {
        // declares 10 element array (of type integers)
        // creates and initializes the array
        int arr[] = new int[10];

        // reading 10 values form user
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter 10 values for array");
        for(int i = 0;i<10;i++){
            arr[i] = scan.nextInt();
        }

        // calculating sum
        int sum = 0;
        for(int i = 0;i<10;i++){
            sum += arr[i];
        }

        // printing sum
        System.out.println("Sum: "+sum);
    } // end of main
} // end of SumArray class
