The quote you posted, is just something you have to keep in mind if you want to be the ideal programmer. Programming is not thinking "what can go wrong", but is think how to do something the best way and program it. If it is a personal project, just write what the method does.
However, there are three possible solutions:
- Do not document the method.
- Think a minute of what your code does and find out what the most common possible unchecked exceptions could be. Add them to the Java-doc. And if you encounters a new one, find out what the problem is and add it as possible exception.
- Do not care about the possible exceptions and document only the exceptions you throw in the method body (like:
if (obj == null) { throw new NullPointerException(); }).
