The main distinction between fail-fast and fail-safe iterators is whether or not the collection can be modified while it is being iterated. Fail-safe iterators allow this; fail-fast iterators do not. Fail-fast iterators operate directly on the collection itself. During iteration, fail-fast iterators fail as soon as they realize that the collection has been modified i. Fail-safe iterates operate on a cloned copy of the collection and therefore do not throw an exception if the collection is modified during iteration.

Servlets are Java technology based components that generate dynamic content, and are considered to be the core building blocks of Java based web applications. Servlets interact with clients through a request and response model that the servlet container implements. A servlet processes the request sent from the client via the servlet container and generates dynamic content that is sent back to the client via the servlet container. A servlet container is part of a web server that contains and manages servlets through their lifecycle. In addition to managing servlets, the servlet container provides the network services over which the request to and responses from the servlet are sent. The servlet container also performs other functions such as mapping requests to servlets, decoding requests to the servlet and formatting responses that are send back from the servlet. A web server can process and respond to HTTP requests for static content, but it cannot process requests for dynamic content by itself.
