null interface is the example of marker interface. Interface are diffrent types. that are mainly extend interface, markble interface and marker interface. diffrence of marker inteface and others are that marker interfaces has no methods..Example are;- serilizable-- for serialization. remote -- for remote method communicaton. your remote interface must extends this marker interface. when ur remote interface extends marker interface then it is called as extend interface.
