public abstract class HandlerException
extends Exception

This class represents one of the fundamental mechanism with which the server work. This is an abstract class, so their abstract methods must be implemented. Abstract methods are already implemented by other classes in this same package, and they all implement the method `getServerAnnouncement()` so that it can be printed and can be easily accessed by the Handler. This way, a HandlerException can be thrown, and only one needs to be handled. For further information, cfr. handle() method in RequestListener
