interface but interviewer was snuff it on pressing on why business office , may move he was but read whatever spider web log postal service near it :). So afterwards the interview my friend comes to me as well as inward commons utter he told me near this questions as well as inquire me the answer. Well this is real classical query like Why String is immutable inward Java; similarity betwixt these ii questions is they are mainly driven past times blueprint determination taken past times java's creator or designer. Though next ii argue brand feel to me on Why Java doesn't back upwardly multiple inheritances:
In my sentiment fifty-fifty if nosotros take the occur caput of diamond degree H5N1 as well as allow multiple inheritances nosotros volition run across this employment of ambiguity.
Some times if yous laissez passer on this argue to interviewer he asks if C++ tin back upwardly multiple inheritance than why non Java. hmmmmm inward that representative I would elbow grease to explicate him the 2nd argue which I direct hold given below that its non because of technical difficulty but to a greater extent than to maintainable as well as clearer blueprint was driving component division though this tin exclusively move confirmed past times whatever of coffee designer as well as nosotros tin but speculate. Wikipedia link has some expert explanation on how dissimilar linguistic communication address employment arises due to diamond employment land using multiple inheritances.
2) Second as well as to a greater extent than convincing argue to me is that multiple inheritances does complicate the blueprint as well as creates employment during casting, constructor chaining etc as well as given that in that place are non many scenario on which yous demand multiple inheritance its wise determination to omit it for the sake of simplicity. Also coffee avoids this ambiguity past times supporting unmarried inheritance amongst interfaces. Since interface exclusively direct hold method proclamation as well as doesn't supply whatever implementation in that place volition exclusively move but i implementation of specific method therefore in that place would non move whatever ambiguity.

Why Java doesn't back upwardly multiple inheritance
1) First argue is ambiguity or so Diamond problem, catch a degree H5N1 has foo() method as well as so B as well as C derived from H5N1 as well as has in that place ain foo() implementation as well as forthwith degree D derive from B as well as C using multiple inheritance as well as if nosotros refer but foo() compiler volition non move able to arrive at upwardly one's heed which foo() it should invoke. This is likewise called Diamond employment because construction on this inheritance scenario is similar to four border diamond, run across below A foo() / \ / \ foo() B C foo() \ / \ / D foo() In my sentiment fifty-fifty if nosotros take the occur caput of diamond degree H5N1 as well as allow multiple inheritances nosotros volition run across this employment of ambiguity.
