Task 3. Implementation of MyMatrixException class In this part you are asked to create your own exception class. (a) Create new class as MyMatrixException extending the class Exception. Provide a constructor for the new class as public MyMatrixException (String msg) , which calls the parent class constructor with msg parameter. (b) An array parameters are valid inputs to a public MyMatrix method if and only if it is a square array of type double [n] [n ] with n > 0 and dimensions are compatible for binary operations. For all the relevant public methods in MyMatrix class add all the necessary code to check for non-valid input, throwing a MyMatrixException with message "Input is null", "Input is not a square matrix" or "Input matrices have different dimensions" as appropriate
