Hi Sagar No not at all, an interface or a class can never extend more than one interfaces or classes. As its gonna completely break the Single Inheritance rule of Java. what do you think..please post if you need more clarification. cheers Nasir

Yes! Any interface can extend any number of other interfaces. This is in contrast to the linear inheritance hierarchy between classes.

http://www.javaprepare.com/quests/test.html At the above URL in Q No. 43, one of the answers is (c) which means that extending from multiple interfaces is possible. Pls have a look and comment on the same.

Look at JLS: 9.1.2 Superinterfaces and Subinterfaces
