Exception Handling

Perhaps exception handling is one of those topics that deserve a lot of attention but get none. Most of the exception handling techniques that I have seen in real-world applications catch everything and then either continue execution with a possibly corrupt state or throw an error to kill the program entirely even if it is not necessary. I know that such code blocks are often written based on the developer’s gut feeling rather than a clear understanding of the exception handling guidelines. Therefore, in this section, I hope to clarify a few critical matters around this topic.
