Description
1 Exceptions and Method Overriding Recall that when a subclass method overrides a superclass method.
• It must have the same signature
• Its return value must be the same or a subclass of that of the superclass method
• Its access mode must be the same or wider than that of the superclass method
In other words, the overriding subclass method
• Can remove an exception class declared in the superclass method header
• Can replace an exception class by a subclass
• But cannot add extra checked exception classes that are not subclasses of the
exceptions declared in the superclass method
