constructor

What is the difference between creating the object within the constructor and outside the constructor?

I'm not sure I understand the question, do you have some code you can give as an example?

I dont feel there is any difference between creating the objects inside & outside a constructor.
Normally when ever a object is created the corresponding constructor or atleast a default constructor is called.

If a class extends from some other class and when ever a object of the child is created, the constructor in the child class automatically invokes the default constructor in the super class & this goes till the top level heirarchy of class.

A constructor doesn't really create an object, it completes the initialization of the object.
