Difference between Servlet and Servlet Instance

Hello ,

I have a very basic question regarding servlet , (which keeps me confusing)

What is the difference between Servlet and Servlet Instance?

I surfed the internet and found the following : -

" The init() method is called once per servlet instance. "

" There are no concurrency issues during servlet initialization, because the server calls the init method once, when it loads the servlet. "

which appear confusing to me.

Can anyone please explain me or let me know some site that has in-depth explanation about servlet life cycle?

Thanks in Advance

There's no difference really. "The servlet" isn't an exact term -- it could mean a servlet instance, or it could mean the servlet class.

Whenever mention is made of a loaded and running servlet, it's a servlet instance that is meant.
