Extra Credit Of 100 points for doing Q3 1. Write a CRC card and a class diagram for a proposed class called Counter. An object of this class will be used to count things, so it will record a count that is a nonnegative whole number. Include methods to set the counter to a given integer, to increase the count by 1, and to decrease the count by 1. Also include a method that returns the current count as an integer, a method toString that returns the current count as a string suitable for display on the screen, and a method that tests whether the current count is zero. Create an interface for the class Counter Suppose you want to design software for a restaurant. Give use cases for placing an order and settling the bill. Identify a list of possible classes. Pick two of these classes, and write CRC cards for them. 2. Extra Credit Of 100 points for doing Q3 1. Write a CRC card and a class diagram for a proposed class called Counter.
