Can someone please suggest book or exercises to understand exceptions? I was working on Java project and I was not productive because I could not understand stand where I should throw errors and which function to catch it. I did not get far and was eventually removed from the project because of the buggy code. I think it happened because i don't understand how to write code using exceptions. What layer of code should i catch exceptions? How to deal nested function calls?
