Write a class called Cup that contains the following information: 1. Private instance variables for the size of the cup (either 8, 16 or 32 ounces (Int)), and the contents of the cup (String) (such as "soda" or "water" or any string). 2. A two-argument constructor to set each of the instance variables above. If the size of the cup is not 8, 16 or 32, throw an IllegalArgumentException stating the argument that is not correct. 3. Get and Set methods for each instance variable with the same error detection as the constructor. public class Cup
