Java Abstract Class Vs Interface

Abstract Class : A class that is declared using “abstract” keyword is known as abstract class. It can have abstract methods as well as normal methods. A normal class cannot have abstract methods.

Interface : Interface looks like a class but it is not a class. An interface can have methods and variables just like the class but the methods declared in interface are by default abstract . Also, the variables declared in an interface are public, static & final by default.
