hi
ServletLoading:
While running your Servlet class,classloader will read the information available in your servlet and places inside classArea(nothing but a memory created by JVM).

ServletCreation:
There are serval cases in creating servlet object.Genaral case is ,when your browser sends first request to the servlet ,the web-container will create the servlet object.
Web-container has the liberty when to create a servlet object and when to destroy it.
