Problem 1: 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.

Transcribed Image Text:Problem 1:
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.
Expert Solution
Step 1
Answer:
we have done code in the programming language and also we have attached editable code and code screenshot and code output
Algorithms:
1. we have create a function that take and arguments matric and their size
2. when inner and outer loop are equal then sum of the digit are called the sum of the major diagonal
3. then print the sum of the diagonal
4. In the main function we have ask to give the user size of row or column
5. after the given the size hen enter the enter the matric element and call the the created function form the main function .
