Java中Enumerator和Enumeration的区别

Question

Can any one please give clarification about these? I am really confused.

Answer 1

Enumeration is process of loop through the collection ( Enumeration ) (Generally called as Enumerator).

Enums are different.

An enum type is a type whose fields consist of a fixed set of constants

Answer 2

Enumeration is an interface :

http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Enumeration.html

An object that implements the Enumeration interface generates a series of elements, one at a time. Successive calls to the nextElement method return successive elements of the series.

Enumerators are a generic term. More of on the lines of Iterator.

Answer 3

Enum - Define a set of constants and use it where ever required.

java.util.Enumeration helps iterate through a set of objects using .nextElement() .
