Parameterized Constructor in Servlet

Question

Is it possible to declare a parameterized constructor inside a servlet that is only a constructor?

If not, why?

Answer 1

No.

Servlet instances are created by the container through reflection, and they expect to find the open no-arg constructor (the default constructor).

To configure the servlet, use the servlet settings specified in the web.xml file. They are passed to your servlet init().

Although it would be possible for the servlet container to choose a non-default constructor and overlay character strings on simple types and invoke the constructor constructively, this is not what the servlet specification requires.
