A Game object knows its name and the number of avators is currently has. It is initialized without Avatars objects. It has a method startGame, which initializes an internal empty list of Avator objects. It has a method to add one Avator object at a time to the Game. It also has a method to remove an Avatar object by the Avatar’s name. A Game object also has a method to animate all its current Avatar objects. Furthermore, it has a method to stopGame, which destroys all current Avator objects in its internal list. The Avatar class creates simple human-type Avatars, which have attributes such as name, hair color, height, superpower. An Avatar object can change its hair color and superpower. It also has a method that “animates” the avatar. The animate() method should simply be a print message such as “Hello! I am …! I have…. hair and my super power is….!”, using the Avatar’s object variables. In main program, create 3 different Avatar objects that resemble 3…

Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.
