assosiative arrays

[Rune Runnestø]

Php and Perl have a structure called assosiative arrays. With keys and
values. Does Java have a similar structure ?

Yes, there's the Map class.

See java.util.Map and its subclasses.
You have to use them as classes - there's no special language
support for them, so instead of (python maybe):
x = properties['WibbleRate']
you must use
x = properties.get("WibbleRate");

Yes - many kinds of; it even has "associative arrays"
that maintain insertion order, which perl doesn't.

See the MANY implementations of Map, both in
standard Java, and many "collection"
type libraries such as Apache/Jakarta
