How to create and remove a session in JSP?

JSP Session uses HttpSession to create a session for each user. To create a session in JSP, we need to use setAttribute from the session implicit object.

Creating Session

session.setAttribute("user", name); //it creates the session for the object name. 

To remove the object from the session.

 
session.removeAttribute("user"); //deletes the session for the object name. 

To remove the entire session.

session.invalidate(); - it kills the entire session and all the objects that are associated with this session.
