i know every default no
argument constructors first
statement is super(); that is its
going to call its super class no
argument constructor. And every
class(i.e. which does not extends a
class) is child class of object. Then
my question is,what is super(); of
Object class doing???

See section 8.8.9 of the Java Language Specification.
The JLS is something you should always check when you have these sort of questions about how Java functions.

Welcome to the Ranch.

Since Object is at the root of the class hierarchy (class Object is the only one which doesn't have a superclass), there's no superclass constructor to call, so super(); would not do anything.
