Differentiate between interface and abstract class in the context of Java.

Answer»

The following table lists the differences between an interface and abstract class:

Interface	Abstract class
Only abstract methods are allowed in an interface. It can also contain default and static methods with Java 8.	There are abstract and non-abstract methods in an abstract class.
We cannot implement the concept of multiple INHERITANCES USING interfaces.	We cannot implement the concept of multiple inheritances using abstract classes.
The implementation of an abstract class cannot be provided by an interface.	An abstract class can provide interface implementation.
Only static and final variables are used in the interface.	Variables in an abstract class can be final, non-final, static, or non-static.
To declare an interface, we use the interface keyword.	To declare an abstract class, we use the abstract keyword.
Only another Java interface can be extended by an interface.	An abstract class can implement numerous Java interfaces by EXTENDING another Java class.
The keyword "IMPLEMENTS" can be used to create an interface.	The keyword "extends" can be used to extend an abstract class.
By default, MEMBERS of a Java interface are public.	Private, protected, and other class members can be found in a Java abstract class.
