First of all there is no such thing called constructor in case of Servlets.
There is an init() method that is called only once while the initialization
of the servlet. For subsequent requests, only the relevant methods to
handle request are called(for example, doGet() and doPost()).
Therefore, for the very first request to the servlet, the sequence of the
method calls on the servlet would be:
1) init()
2) service() (and then may be doGet or doPost method based on whether you
have implemented the HttpServlet abstract class)
However, for subsequent requests:
1) service() method is called (and then may be doGet or doPost methods based
on whether you have implemented the HttpServlet abstract class)
Hope this clears your doubt!
