27/05/2014 · The Java Dictionary class is an abstract class that allows all its derived classes to store data in the form of key-value pairs. Both keys and values can be objects of any type, but keys should be unique. Also, both keys and values cannot be null. For instance, if a key or value is referring to null and then inserted into a dictionary, a Dictionary is an abstract class that represents a key/value storage repository and operates much like Map.
