one should not use the clone  method from within the class  itself. clone
is used when u want to create identical replicas of the same object  in
some other class not the same class. even though u may be able to do
that, it is not the right way of doing it.

there are cleaner ways of doing this. the problems u r facing could be
because u r passing references to ur constructor  inside clone method  and
when u modify the values of these references all the values are changed
in the new and the old object

try to avoid the clone stuff if this is what u want to accomplish.

I'm need something like this.
If i have a class

UserBean objUserBean = new UserBean();

--> UserBean has a getNumber() method

I need to work with it but in a general form like

Object obj = new UserBean();

--> i need obj.getNumber()

Some idea like the reflection, have any example to work with
