If you do not have exception handling under control, you risk that your applicationor data ends up in an unhealthy state, which can have serious consequences. Therefore,knowing how to implement proper exception handling is a must for every Java developer.

This bookis a good step on the road to learning that, although any developer should keep learning morethroughout their whole career.I have tried to make this book as concise as possible. However, some explanations are maybe longer than what a developer with 10 years of experience needs, in order to make sure that developers with 2 years of experience understand them. Having said that, all suggestions for improvement are appreciated. My email address is in the book.This book contains 4 parts. Part 1 describes the basic exception handling mechanisms providedby the Java language. Part 2 lists the requirements for exception handling at the applicationlevel.

Part 3 explores how to implement exception handling in applications to meet therequirements set forth in part 2. Part 4 goes into more detail about what diagnostic informationyour applications should gather and include when throwing and logging exceptions.The book is intended for Java developers with 2 or more years of experience in Java development.It is not a beginner book.Table of ContentsPart 1: Basic Java Exception Handling Techniques- What are Exceptions?- Try Catch Finally- Try-with-resources- Catching Multiple Exceptions- The Call Stack- The Execution Path- Throwing Exceptions- Propagating Exceptions- Exception Hierarchies- Custom Exceptions- The Exception Class- Exception Handling Templates- Checked vs.
