Yooooo guys,

I am having a HashMap here. Now I want to retrieve all the values from it. But I want to retrieve them in the order in which I put them in. Is this possible in an easy way ?

Cheers,
Wim

LinkedHashMap. Added in JDK 1.4.

Yes you can, but not with the standard set of collections classes provided as part of the standard Java API.

The Jakarta Commons Collections component provides a SequencedHashMap class that implements the standard Map interface that should provide the functionality that you require.
