Sum of First and Last Elements

The array {10, 20, 30, 40, 50} is given. Print the sum of only its first and last elements with System.out.println (see Expected Output).

The last element is at index arr.length - 1, not arr.length. Do not hardcode 60.

Expected Output:

60↵

= newline. The output ends with a newline — print one after the last line.
