You can't find them all anywhere. You'll just encounter them as you use different APIs.
One of the most basic concepts around exceptions has to do with the difference between checked and unchecked exceptions. Any exception that extends RuntimeException is unchecked. Which means that if you call a method that throws an unchecked exception, you don't have to provide a catch block. These exceptions are usually thrown for things that could be avoided, i.e. programmer error.
The compiler will require you to have a catch block for all checked exceptions. This means you should take steps in your code to handle them and retry the operation, such as user errors.
