I have provided you with 3 interfaces (HasLegs, HasWings, and BreathesUnderwater) and a Tester class. I want you to create 6 new classes: • 2 that implement HasLegs • 2 that implement HasWings • 2 that implement BreathesUnderwater For each of the classes, you will have to implement the methods that the interface dictates. In addition, override toString so that it prints out a simple message describing what the object is. See the example output of my implementation below for an idea how to do that. The Tester class creates 3 ArrayLists, one for each interface. It also loops through each ArrayList and prints out its contents using toString and the interface methods. In between those two chunks of code, you’ll see a //TODO: comment. It is there that I want you to create one object for each of the 6 classes you created and add that object to the appropriate ArrayList. Once you have done all that, you should be able to run your program and see output like the following: I am a table. I have 4 legs. I am a human. I have 2 legs. I am an airplane. I have 2 wings. I am a bee. I have 4 wings. I am a fish. I am breathing underwater. blub, blub... I am a scuba diver. I am breathing underwater. Help! I'm sentient and trapped in a computer program!
