Hi to all Please anybody tell me Why is there an init()method ? In other words ,why is not the constructor enough for initializing a servelet? Please explain in detail and with example if possible.
This is given in HFSJ at page no. 102 but i am unable to understand it(means not got it).

So that we can happly override it, without bothering to call super.init(ServletCOnfig)

While Aditya's answer is correct, it's only half the story.
The method that is part of the Servlet interface is init(ServletConfig config). Its purpose it to pass a ServletConfig object to the servlet (which is needed to perform number of things in the servlet). Since an interface can't specify that there needs to be a constructor with this parameter, it was made a method.
