Abstract :

If you want to implment only few methods in the concrete class may or may not ovveridable the methods then use abstract.

Interface:

If you want to implement all the methods designed from interface in the concrete class use interface and also it is used to write loosely coupled programs.

Interface is a purely abstract class designed by implicitily.

Abstract and interace it is used develop a system in a oops design guidlines apart from logic.

You should use an abstract class if you need to supply a base implementation.
Otherwise, use an interface.
