Module 04 · Exception Handling

Objective group 4: how Java signals and recovers from failure — the Throwable hierarchy, checked vs unchecked exceptions, try/catch/finally, multi-catch, try-with-resources, and custom exceptions. The exam loves the subtle control-flow questions (finally overriding a return, suppressed exceptions), so watch those.
