I have been in both situations:
In both cases the project started OK but soon became an overhead to maintain (and refactor).
So what is the best practice regarding the creation of your own Exception classes?

To create a custom exception, we have to extend the java. lang. Exception class. Note that we also have to provide a constructor that takes a String as the error message and called the parent class constructor.
The exception handling fundamentals in Java revolve around the five keywords- try, catch, finally, throw, and throws. These keywords form the base of exception handling. All the exception handling mechanisms in Java are a result of these five keywords.
The Java Specialists wrote a post about Exceptions in Java, and in it they list a few "best practices" for creating Exceptions, summarized below:
Don't Write Own Exceptions (there are lots of useful Exceptions that are already part of the Java API)
Write Useful Exceptions (if you have to write your own Exceptions, make sure they provide useful information about the problem that occurred)
