Enumerator Vs Iterator

Hi,

What is the difference between Enumerator and Iterator?
Where we use Enumarator and where we use Iterator?

Any one Please help me...

The main difference is Enumerator does not provide a standard method for
for removing tehe objects.
Iterator has provided method for removing the objects.

Well to start off with there is no class/interface in java called as Enumerator. Though there is Interface called Enumeration.

Iterator takes the place of Enumeration in the Java collections framework. Iterators differ from enumerations in two ways:

1) Iterators allow the caller to remove elements from the underlying collection during the iteration with well-defined semantics.
2) Method names have been improved.
