Complete the sumOfDiagonals method in SumOfDiagonals.java to do the following public class SumOfDiagonals { public static void main(String[] args) { String[][] s1 = {{"2", "3", "4"}, {"5", "6", "7"}, {"8", "9", "10"}}; String[][] s2 = {{"1", "2", "3"}, {"5", "6", "7"}, {"9", "10", "11"}, {"13", "14", "15"}}; String[][] s3 = {{"1", "2", "3", "4"}, {"5", "6", "7", "8"}, {"9", "10", "11", "12"}, {"13", "14", "15", "16"}}; try { sumOfDiagonals(s1); sumOfDiagonals(s2); sumOfDiagonals(s3); } catch(NumberFormatException ex) { System.out.println("Not a valid integer"); } catch(IllegalArgumentException ex) { System.out.println("Array not a square"); } } public static void sumOfDiagonals(String[][] x) { //TODO Complete this method as required in the homework instructions } }
Argument Array x
{{"2", "3", "4"},
{"5", "6", "7"},
{"8", "9"

Complete the sumOfDiagonals method in SumOfDiagonals.java to do the
following:
The method takes a 2D String array x as a parameter and returns no value.
The method should calculate and print the sum of the elements on the major
diagonal of the array x.
In order to have a major diagonal, the array passed into the method should
be a square (n-by-n), if it's not a square your program should handle that
situation by throwing an exception. (Do Not worry about ragged arrays)
If the array is a square, but there is a non-integer value on the major
diagonal, your program should handle that situation by throwing an
exception.
When handling the exceptions, be as specific as you can be, (i.e. Do Not just
use the Exception class to handle all exceptions in one catch block).
Make the proper calls to the sumOfDiagonals method from the main
method to test your sumOfDiagonals method on all the String arrays
provided in the main method.
Sample runs provided on the next page.
