Java: January 2005 Archives

I guess there would be three groups of Java developers out there - those who know about exceptions but have never heard of checked and unchecked exceptions, those who know what it is but do not understand them and those who truly know and understand them.

When should you perform input validation, and how thorough should you be? This is a question many developers are struggling with.

I am pretty sure once you transcend the youth phase of software development, and you start thinking about what you are actually doing whilst writing code, you'll start running into tough decisions such as when to throw an exception, and when to return null.
