Create a interface without any method and variable in that...
That makes the interface as marker.
though i guess that there is no formal defination of marker interface.

Marker Interface will be used, when you want mark your Class saying it is serlizable or colneable?
Likewise you can create an Interface like Rahul said, If you have such a kind of requirement.

Note that marker interfaces are an old "hack". If you are using Java 5.0 or newer you should use annotations instead of marker interfaces.
See for example An Introduction to Java Annotations and Of Java Annotations to learn what annotations are.
