java inheritance

every body aware object class is super class of every class in java.
means every class extends the Object class.
class A extends B{} already extends Object class in this a can have
properties of both object and b class how this is posible even though java
doesn't supprot multiple inheritance.

Not an advanced question. Moving...

Class A inherits from the Object class as a result of extending class B because class B is an Object. A does not extend both ClassB and Object. So you have a linear hierarchy like so

Object-> Class B --> Class A.

Speaking of multiple inheritance, if you ever feel that you need it, you can declare your class to imiplement interfaces in addition to inheriting from a single parent class.

That's not inheritance, it's implementation...

btw, Java does support multiple inheritance but only of interfaces.
