The servlet container loads the servlet during startup or when the first request is made. The loading of the servlet depends on the attribute of web.xml file. If the attribute has a positive value then the servlet is load with loading of the container otherwise it load when the first request comes for service. After loading of the servlet, the container creates the instances of the servlet.

Initialization :Initialization is the first phase of the Servlet life cycle and represents the creation and initialization of resources the Servlet may need to service requests. All Servlets must implement the javax.servlet.Servlet interface. This interface defines the init() method to match the initialization phase of a Servlet life cycle. When a container loads a Servlet, it invokes the init() method before servicing any requests.
