Topic: Beyond Error Handling : Using Design to Prevent Errors
It would be easy to say that error handling is a black art in software development but that implies that there is some secret stash of knowledge out there. The truth is that we tend to think of error handling as a “lesser concern.” If we know how to throw and catch exceptions, we feel that we are okay. The fact of the matter is we aren’t okay. Error handling in applications is often a symptom of incomplete design. This course will focus on techniques you can use to systematically increase the robustness of code by rooting out potential errors and designing them away.
