The fact about Java is that it does not support the multiple inheritance.

But I have a question that the base class of all java classes is Object.

Answer 1

The concept of Multiple Inheritance means, that you can have a class A, B and C where A is derived from B and C like this:

class A extends B, C {}

This is not possible in Java.

What you describe is a straightforwar inheritance with a direct line of descendenats.

class A {};
class B extends A {}
class C extends B {}

You don't really need Multiple Inmheritance though, because with Interfaces you can basically achieve the same in a much cleaner way.
