Why shall we use an empty interface(marker interface)?
Is there any specific use if there are no methods in the interface?

A marker interface is a interface with emplty methods/behavior. One of its purposes is to tag the classes implementing this interface. mainly this is used to group classes of the interface type.
In this case, any instances of the class are valid instances of interface.
