The declaration of the class ChainedScatterTable is given in Program . The scatter table is implemented as an array of elements of the nested type Entry. Each Entry instance has two member variables--object and next. The former is a pointer to a contained object. The latter indicates the position in the array of the next element of a chain. The value of the enumerated constant null will be used instead of zero to mark the end of a chain. The value zero is not used to mark the end of a chain because zero is a valid array subscript.
