if i have a class that can extend abs class n implement interface...and it doesnt have to achieve inheritance ,doesnt hav to extend any other class then which 1 should i use between extending a abs class with abs method or implementing interface with abs method.?/:confused:
pls ans
not sure if the question is clear enough... but i will try:
if you implement the interface - you will have to rewrite the method/s.
if you exted - u can call existing code without writing anything.
If I understand the question correctly - "doesnt have to achieve inheritance " -
you probably mean that we dont have to use any existing method of the original class.
therefore - I would go with implementing the interface.
I am not sure whether I understood your question or not!!.
But I want to share with you something.
If you want to make a class or method that can not be extended by other
classes. then declare that class or method as [B]final[/B]. then that class
or method cannot be extended by other class
sorry frens.i think u didnt get my question.I am explaining again..
I got this question in an interview.:confused:
Which 1 i will choose if given a choice between extending an abstract class and implementing a interface ..which 1 I should opt.
NB:Class which ll either extnd or implement doesnt have any other requirements.
Pls ans i hope its now clear...
Thanks 4 ur replies.
