Examples of marker interfaces are:

Hi suresh thanks for that answer but tell me is it exact definition for Marker interface that any interface having no methods is marker interface
and is java.lang.Comparable is marker interface?
thanks in advance

Comparable is not a marker interface as it has one method

int compareTo(Object o).
