i would like to know about interface and abstract classes.
i read as
you need some classes to use some methods which you don't want to be included in the class, then you go for the interface, which makes it easy to just implement and make use of the methods defined in the interface.

abstract classes when
Abstract classes are an excellent way to create planned inheritance hierarchies. They're also a good choice for nonleaf classes in class hierarchies.

I am not clear on this this explanation. Thanks in advance
