An interface class is a class contains all functions that are are abstract.

An abstract class is a class that may or may not contain an abstract function.

Abstract function : functions with only declaration , no definition is present. the user implimenting, inheriting the function has to override the function , mandatorily.

Instances of abstract class and interface class are made at runtime.so objects cannot be created ,due to lack of informations of the class. Source: CoolInterview.com
