Add Numbers inside an Array : JAVA OOP



Write Java Source code: How to Add Numbers inside an Array using For Loop




Sample Output:

Enter the size of the input you want to enter: 5
Enter 5 numbers: 2 5 3 7 25
The sum of the numbers is:42

Source Code:





//java class


public class ArraySum
{
    public int sumOfArray(int[] array)
    {
        int sum = 0;
        for(int i=0; i<array.length; i++)
        {
            sum = sum + array[i];
        }

        return sum;
    }
}

//main class


import java.util.Scanner;

public class Main
{

    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the size of the input you want to enter: ");
        int size = input.nextInt();
        int[] numArr = new int[size];
         
        System.out.print("Enter "+ size +" numbers: ");
        for(int i=0; i<numArr.length; i++)
        {
          numArr[i]=input.nextInt();
          
        }

        ArraySum access = new ArraySum();
        System.out.print("The sum of the numbers is:" + access.sumOfArray(numArr));       

    }
}
