This module discusses a key part of the Java language and libraries: exceptions. Exceptions are Java's way of reporting and working with errors. They allow programmers to explicitly and formally define a control flow for errors, and they separate error detection from error handling.

By the end of the module, you should be able to:

1. Describe why exceptions occur
2. Catch exceptions
3. Throw exceptions
4. Make your own exceptions
5. Be able to use the finally keyword
