What will happen inside init() in servlet. my interviewer
asked servlet lifecycle. i said "once servlet is loaded in
to memory init() will be called which performs servlet
initialization " . Again interview asked what values will be
initialized . what is difference between init() and
init(ServletConfig config).
Answer Posted / manidhar
Your superclass includes two versions of init(),one that
takes a ServletConfig and a convenience version thats no -
arg. The3 inherited init(ServletConfig) method calls the no-
arg init method, so the only one u need to override is the
no-arg version.
no law that stops u from overriding the one that takes a
ServletConfig,but if u do then u better call super.init
(ServletConfig) but theres really NO reason why u need to
override the init(SC) method, since u can always get ur
ServletConfig by calling inherited getServletConfig()
method.
correct me if am wrong
