The purpose of hidden fields, cookies and session objects is to transfer data between different pages of an application.

I agree with Mr. Goyal.
I hope you know that HTTP is a stateless protocol and so are our web applications.They can't remember the data of client across multiple requests of an user(which is called as session).
All the above three are the techniques that are used to enable session tracking in servlet based web app.

To send data from one web page to another without being shown to the user hidden fields are used.

Http Protocol is a stateless protocol hence it does not remember previous request and the variables and it treats each request as the new request. In order for it to remember the previous request data cookies and sessions are used.
