Ok so even though Animal extends Mammal and has inherited the controlTemp() method from Mammal, only the methods in Lion and the methods in the original methods in Animal can be accessed.

[@BillBarnum]

Mammal is a subclass of Animal, so we would say that Mammal extends Animal. Animal is a superclass of Mammal, so Mammal can inherit from Animal, but not the other way around. controlTemp is part of the Mammal class so Mammal has access to it. Lion is a subclass of Mammal, so Lion would inherit it from Mammal.

@@BillBarnum Ok thanks! I actually watched a couple more of your videos and understood it a lot better.

[@harshsharma57]

nice video , btw in Java i think you cannot have more than one subclasses of a class @1:06

[@BillBarnum]

Hey Harsh, Java classes can have many SUBclasses, but can only have one SUPERclass.
