Answer / ravinder
When a class implements a marker interface, then the object
of that class is given with a special behavior. For example
if a class implements remote interface(available in
java.rmi.* package) object of that class acts as a Remote
Object. For this reason java provides Marker Interface.

Answer / siva kumar g
Marker interfaces can create an environment.
Marker interfaces are used to specify that a class belongs
to a logical family or grouping - as quoted above,
Cloneable is used to indicate that a particular class can
be cloned, or Serializable is used to indicate that a
particular class can be serialized.

Answer / maurya
an interface without any method is known as marker
interface. we use marker interface to actually mark for JVM
to distinguish that the class is belongs or subclass of ant
particular super class.
EX-->
we have an interface named serializable. there is a
condition that if you want to serialize your object u must
have to implements marker interface.
by doing this we just only inform JVM that my class is able
to be serialized. JVM detact it at run time by using Class
class methods.
