When working on a project where in you have to add features to an existing code written by other members of your team, you may have encountered problems understanding parts of the code. Sometimes the problems are caused by codes not well commented or sometimes the codes are simply unreadable.

Take this code for example:

int x = Integer.parse(request.getParameter("x").toString());

Many software developers today are still using the old way of "write your own code" strategy. Although it may seem right for a developer's perspective in terms of skill enhancement and originality, when it comes to developing large-scale applications on a tight deadline, this may not seem to be the best approach.

If you were running apache tomcat server in your web server then most probably you face some problem on serving some of your servlet and jsp pages. One of the problems I encounter before with tomcat server is it’s hard to install. Especially if you are not an expert user in Linux operating system.

What is an Exception?

Definition:

“When an unusual, irregular, abnormal or nonstandard condition arises in a sequence of code at run time this phenomenon is referred as Exception handling”

An exception is a runtime error.
