A web application uses the HttpSession mechanism to determine if a user is "logged in." When a usersupplies a valid user name and password, an HttpSession is created for that user. The user has access tothe application for only 15 minutes after logging in. The code must determine how long the user has beenlogged in, and if this time is greater than 15 minutes, must destroy the HttpSession.
Which method in HttpSession is used to accomplish this?()
A.Getcreationtime
B.Invalidateafter
C.Getlastaccessedtime
D.Getmaxinactiveinterval
