Difference between request.getSession().getId() and request.getSession(false)?

Question

What do these calls actually mean in terms of session?

System.out.println(\"print1: \"+request.getSession().getId());
System.out.println(\"print2: \"+request.get         


        

Answer 1

request.getSession().getId()

Returs the id of the session.

Request.getsession(false) returns the already existing session object. It wont return anything i.e. Will return null , if session does not exist. Whereas with true parameter it will create a new session object and return it if no session exists
