Java dictionary is an inbuilt class that helps us to form different key-value relationships. It is an abstract class which extends the  Object class and is present in the java.util package. The Dictionary class is an  abstract parent of any class, such as the Hashtable, which maps the keys to values. Every key and every value is the object in anyone.

Java dictionary can also be termed as a list of pair values, where the pair consists of the key and the value. The relationship of the key to the values is somewhat similar to mapping. First, we map the key with the value, and then afterward, we can again retrieve the value with the help of the key.
