what is use of marker interface? give me good example?..

Answer / aravind

In java language programming, interfaces with no methods are
known as marker interfaces. Marker interfaces are
Serializable, Clonable, SingleThreadModel, Event listener.
Marker Interfaces are implemented by the classes or their
super classes in order to add some functionality.

Suppose the interface Clonable is neither implemented by a
class named Myclass nor it's any super class, then a call to
the method clone() on Myclass's object will give an error.
This means, to add this functionality one should implement
the Clonable interface. While the Clonable is an empty
interface but it provides an important functionality.
