java - Why is ServletConfig obj passed to init() of GenericServlet when the class implements the interface? -

genericservlet implements servletconfig interface means interface functions can invoked init() function of genericservlet. given context, why servlet container sends servletconfig object init() method? know if servletconfig object passed genericservlet.init(servletconfig) different genericservlet object.

regards, ravi

the genericservlet implements servletconfig methods delegating config object passed init method. implements servletconfig convenience - delegates. instead of calling getservletconfig().getinitparameter() can call getinitparameter()
