Can servlet have a constructor ?

Servlet can have a constructor. But you never call the constructor for the servlet / instantiate them , because the container handles it.
So you are better of doing initialization / one-time setup code in the init method of the servlet. Also, the container passes the ServletConfig object to the servlet only when it calls the init method. So ServletConfig will not be accessible in the constructor.However, you might still need the init parameters, so initialization is done in init instead of a constructor.
