What is a Marker Interface? - An interface with no methods. Example: Serializable, Remote, Cloneable
What is the difference between interface and abstract class? - Abstract class defined with methods. Interface will declare only the methods. Abstract classes are very much useful when there is a some functionality across various classes. Interfaces are well suited for the classes which varies in functionality but with the same method signatures.
What is an Interface?
An interface is a contract in the form of a collection of method and constant declarations. When a class implements an interface, it promises to implement all of the methods declared in that interface. Interfaces are useful for capturing similarities among unrelated classes without artificially forcing a class relationship, declaring methods that one or more classes are expected to implement and revealing an object's programming interface without revealing its class. Java uses 'interface' and 'abstract Class' to define interfaces.
