Toward Exception-Handling Best Practices and Patterns

An exception condition occurs when an object or component, for some reason, can´t fulfil a responsibility. Poor exception-handling implementations can thwart even the best design. It´s high time we recognize exception handling´s importance to an implementation´s overall quality. Agreeing on a reasonable exception-handling style for your application and following a consistent set of exception-handling practices is crucial to implementing software that´s easy to comprehend, evolve, and refactor. The longer you avoid exceptions, the harder it is to wedge cleanly designed exception-handling code into working software. To demystify exception-handling design, we must write about - and more widely disseminate - proven techniques, guidelines, and patterns
