Implementing a maker interface is an indication to the java execution environment to provide the class with the hidden functionality for which the interface has been developed. For example Serializable interface

If we implement Serializable interface which does not have any method in it, so is a marker interface. The execution environment takes care of serilaization of the instances of the class which implements the serializable interface. So we can say that corresponding to a maker interface java has provided some hidden functionality which has been plugged into the execution environment.

We can write marker interface but its functionality(hidden) have to be pluged into the execution environment which may to hindrance to java's platform independence

yes you can write marker interface.
A marker interface is the one which doesn't have any methods declared in it e.g. Serializable etc.

Here you go as marker interface...............
interface thisIsAMarkerInterface
{
}
