Cursors are used in Java to iterate or loop through a collection of objects.

The enumeration interface is one of the predefined interfaces, whose object is used for retrieving the data from collections framework variables ( like Stack, Vector, HashTable, etc.) in a forward direction only and not in the backward direction. This interface has been superseded by an iterator.

The Enumeration Interface defines the functions by which we can enumerate the elements in a collection of elements.

For new code, Enumeration is considered obsolete.

However, several methods of the legacy classes such as vectors and properties, several API classes, and application codes use this Enumeration interface.

Important Features:

Enumeration is Synchronized.
It does not support adding, removing, or replacing elements.
Elements of legacy Collections can be accessed in a forward direction using Enumeration.
Legacy classes have methods to work with enumeration and return Enumeration objects.
