VERY EASY Code modification! Please read instructions at the bottom of the Java Code! You are free to use whatever idea or way you want to meet the requirement.

Use the Java hierarchy my code above and add a user-defined exception that can be thrown by one of the methods as part of the validation or error checking. The main method should then make a instance of the class and call the method in such a way that the exception is thrown (e.g. invalid input or state of the system). Include a screenshot of the running modified code output. Please have all the code neatly in 1 file titled Widget.Java
