Embracing an exception


The Exception class includes various methods that help you better understand why an exception was thrown. You can even find out the type of exception, what line of Apex code caused the exception, and even get the entire stack trace. In addition to the built-in exception types, Apex includes the ability to create your own exception types. This allows you to catch a system exception, evaluate it, and throw your own custom exception. Although it involves slightly more work, a custom exception type can be the difference between frantically debugging code in the middle of the night and sleeping like a baby.
