Can we use the constructor, instead of init(), to initialize servlet (Servlets)

Question :Can we use the constructor, instead of init(), to initialize servlet? (Servlets)
Answer :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.
