inheritence

[karthika gkumar]

in java all the classes are extend with Object class implicitly.
java does not support multiple inheritence.
but when we are extending a class with some other class doesnt that mean that class is extended twice?

Hi,

Welcome to JavaRanch!

Multiple inheritance specifically means inheriting from several classes directly. A class can have only one direct parent class. The fact that the parent has its own parent doesn't matter.

the correct statement would be
in java all classes that do not extend from any other class extend from the Object class so if your class in extending from some other class it will not directly extend from Object... so there is no multiple inheritance problem..

I would like to add some more.
it is called maultilevel inheritence which you are explnig exctly.
when we say multiple that means extends morethen oneclass. as you may see in C plus plus.
if we extend two class to one single class by extending 2-times then it is not not fair.
