Marker interface is tagged interface with no methods inside
it.clone means copy of an object.
The marker interfaces are used to provide certain
functionality to classes you code. Take for
instance the Cloneable interface. This interface is
implemented by the JVM itself and allows
copies of objects to be created without the developer having
to write code for this purpose.
User written marker interfaces can also be used for
inheritance purposes.Marker Interfaces are
used to mark the capability of a class as implementing a
specific interface at run-time.
Some examples of marker interfaces are :-
1) Serializable
2) Cloneable
3) RandomAccess
4) SingleThreadModel
5) EventListner
