Q1. Write Java code to implement the UML diagram below. Note the following: a) All italic classes are abstract. b) No need to include any method except those you have to include. c) The howToFly () method should print one line describing how an object flies. For example, a Copter will "fly off the ground vertically using rotor blades." d) Don't implement howToFly () in the Plane class (as it will make little sense because subclasses fly differently). Instead, implement howToFly () in both Copter and Boing777. e) Cars are comparable based on their manufacturing year. f) You don't have to write the body of all classes (e.g. Train would be an empty class), but feel free to adjust the design and add any class members of your choice. > Comparable > Flyable thowToFly(): String > Cloneable Vehicle Bird year:int tage: int Car Train Plane Dove +Dove(age:int) Penguin +Car(year:int) Copter Boing 777
