Explanation

The setMaxInactiveInterval() method sets the maximum time in seconds before a session becomes invalid. The syntax of this method is as follows: public void setMaxInactiveInterval(int interval) Here, interval is specified in seconds. The isNew() method of the HttpSession interface returns true if the client does not yet know about the session, or if the client chooses not to join the session. This method throws an IllegalStateException if called on an invalidated session. Answer: B is incorrect. The getAttribute(String name) method of the HttpSession interface returns the value of the named attribute as an object. It returns a null value if no attribute with the given name is bound to the session. This method throws an IllegalStateException if it is called on an invalidated session. Answer: A is incorrect. The creation time of a session can be obtained using the getCreationTime() method of the HttpSession.
