i HAVE A QUESTION PLZ ADVICE....
Subclasses of an abstract class that do not provide an implementation of an abstract method, are also abstract??

Such a class does not compile.
If you mark them as abstract, though, they will compile. There's no such thing as a non-abstract class that inherits from an abstract class and does not provide implementations of its parent's abstract methods.

In other words, the first concrete subclass of an abstract class should implement all the methods in the abstract parentclass.
