Dictionary (Java SE 11 & JDK 11 )

The

Dictionary

class is the abstract parent of any class, such as

Hashtable

, which maps keys to values. Every key and every value is an object. In any one

Dictionary

object, every key is associated with at most one value. Given a

Dictionary

and a key, the associated element can be looked up. Any non-

null

object can be used as a key and as a value.

As a rule, the equals method should be used by implementations of this class to decide if two keys are the same.

NOTE: This class is obsolete. New implementations should implement the Map interface, rather than extending this class.
