Difference
1. Interface doesn't allow accessibility modifier where as
we can specify accessibility modifier (public, private,
protected) for an abstract class.
2. Interface doesn't provide the implementation of the
members declared. This is not the case with abstract class
3. A class can inherit one and only one abstract class,
where as a class can implement one or more interfaces
