Here is a program in Java that sums up all array element and print out the result to the console.

class Main {
    public static void main(String[] args)
      int[] arr = {1,2,3,4,5};
      int total = 0;
      for (int i = 0; i < arr.length; i++)
         total += arr[i];

      System.out.printf("The sum of array elements is: %d%n", total);
Note: the program will throw the error “incompatible types: String cannot be converted to int” if the array contains elements that are not summable, such as string elements
