Marker interface plays vital role even though it doesn't
contain any methods.The main purpose is to identify the
special objects from normal objects for example if you want
to serialize an object then how you will inform to the JVM
to serialize the particular object because there may be so
many objects available in JVM. In order to know which object
is to be serialized marker interfaces are used. When you
implement a marker interface the object will be tagged with
boolean property with that property JVM knows which object
should be serialized and which object should not be serialized.
