Sum of Array Elements JAVA

// Calculate the sum of all elements of an array

class Main {
 public static void main(String[] args) {
  
   // an array of numbers
   int[] numbers = {3, 4, 5, -5, 0, 12};
   int sum = 0;

   // iterating through each element of the array 
   for (int number: numbers) {
     sum += number;
   }
  
   System.out.println("Sum = " + sum);
 }
}

Finding the Sum of an Array in Java

    static int arr[] = { 12, 3, 4, 15 };
 
    // method for sum of elements in an array
    static int sum()
    {
        int sum = 0; // initialize sum
        int i;
 
        // Iterate through all elements and add them to sum
        for (i = 0; i < arr.length; i++)
            sum += arr[i];
 
        return sum;
    }

sum of array in java

Input : arr[] = {1, 2, 3}
Output : 6
1 + 2 + 3 = 6

Input : arr[] = {15, 12, 13, 10}
Output : 50
15 + 12 + 13 + 10 = 50
