    Re: Constructors in servlet concept

    we can use constructor in servlet for initialization , also you can write your own constructors. For example

    class sample extends HttpServlet
    {
    sample()
    {
    System.out.println("I am Constructor in servlet");
    }
    public void doGet(HttpServletRequest req,HttpServletResponse res)
    {
    sample obj=new sample();
    }
    }

    hi


    Yes, of course you can use the constructor instead of init(). There's nothing to stop you. But you shouldn't. The original reason for init() was that ancient versions of Java couldn't dynamically invoke constructors with arguments, so there was no way to give the constructur a ServletConfig. That no longer applies, but servlet containers still will only call your no-arg constructor. So you won't have access to a ServletConfig or ServletContext. Plus, all the other servlet programmers are going to expect your init code to be in init(). Why confuse them?


    Bye
