Your assignment is to create a class called CharacterList in a file called CharacterListjava. (there is no main method in this class). A class CharacterList has the following instance variables (they must be declared using private) charAmay-an array of characters count an integer The variable count keeps track how many characters are stored in the array. The variable name for the array of characters is charArray. Note: You need to distinguish the array size (capacity) and "count" that keeps track of characters added to this array so far. The class CharacterList must include the following constructor and methods. (If your class does not contain any of the following methods, pointswill be deducted.)
