In Java. Define the class InvalidSideException, which inherits from the Exception class. Also define a Square class, which has one method variable -- an int describing the side length. The constructor of the Square class should take one argument, an int meant to initialize the side length; however, if the argument is not greater than 0, the constructor should throw an InvalidSideError. The Square class should also have a method getArea(), which returns the area of the square. Create a Driver class with a main method to test your classes. Your program should prompt the user to enter a value for the side length, and then create a Square object with that side length. If the side length is valid, the program should print the area of the square. Otherwise, it should catch the InvalidExceptionError, print "Side length must be greater than 0.", and terminate the program. The words for output is highlighted in grey and yellow in the blue box. Class should be named Driver, as shown in blue box as well.
