Java Exceptions: Zero to Hero
A plain-English, example-first guide to Java exception handling in 16 modules — what an exception really is, checked vs. unchecked, try/catch/finally flow, catching multiple exceptions, try-with-resources, throw vs. throws, building custom exceptions, exception chaining, the 10 exceptions you'll meet every day, uncatchable errors, common gotchas, best practices, and real-project patterns — plus two rounds of interview questions and a one-page cheat sheet.
Exception handling is one of those topics everyone thinks they know until an interviewer asks about exception chaining or a try-with-resources edge case. The "10 exceptions you'll meet every day" chapter is the most practically useful part — it's what you'll actually debug in production, not just interview trivia. Good for a focused refresh; not meant to be your only Java resource.
