The main difference between abstract class and interface in Java is that the abstract class is used to implement abstraction while interface is used to implement abstraction as well as multiple inheritance.. One major pillar in Object Oriented Programming (OOP) is Abstraction. It is the process of hiding the implementation details and displaying only the functionality to the user. Abstract classes, on the other hand, provide an identity to the classes that derive from them, as they inherit their behaviors from it. Summing up, we can say that the major difference between an abstract class and an interface is the methods they contain (completed versus uncompleted) and their contents (a real class vs. an empty template).
