marker interface is tagged interface with no methods inside 
it.clone means copy of an object

Marker interface is interface which doesn't have nay method 
but still holds information..
Ex: Clonable

marker interface is a class in garbage collection and clone 
is the bit wise copy of an object

Marker Interface is a interface which does not have methods 
and also one more point is that it makes the method to 
execute compulsory.Example Runnable Interface we call it as 
a Marker Interface but as per the First Point it should not 
be a Marker Interface but it contains a run() and when u r 
extending the Thread Class it is making u to execute run() 
Indirectly.

So my dear friends when u r argue abt some topic plz be 
clear with it and then argue.
