how to study inheritance and polymorphism: create long study guides in which you make a series of inherited classes about elves

public class Elves
public class Noldor extends Elves
public class houseOfFeanor extends Noldor
public class houseOfFingolfin extends Noldor
public class houseOfFinarfin extends Noldor

Noldor Galadriel = new houseOfFinarfin()
Noldor Fingon = new houseOfFingolfin()
Noldor Maedhros = new houseOfFeanor()

i’m too tired for this
