APIFest08:Task2

From APIDesign

The task2 of APIFest08 is here. We have fourteen solutions that advanced to second round. Some of them did use their chance to get up to speed in APIFest08:Task1.5, some of them did not. The latter ones will be in tougher position, as the second round is just about to start.

You task #2 is to allow one convertor to hold multiple rates of multiple currencies. Also, create an API to allow composition of convertors. Here is the Task2Test.java file with detailed description of the quest. Locate your solution among existing task2 directory, copy the Task2Test.java file along your Task1Test.java. Enhance your API, show its usage in the Task2Test.java.

After you are done, please generate a diff. The best way is to use Mercurial:

# create the repository
hg clone http://source.apidesign.org/hg/apifest08/
# or update it
hg pull; hg update
# copy the task 2 file
hg copy currency/test/org/apidesign/apifest08/test/Task2Test.java task2/solutionXY/test/org/apidesign/apifest08/test/Task2Test.java
# then do your modifications
# ...
# and finally produce a diff
hg diff

you can obtain the diff in other ways, potentially you can send us to our mailing list the whole ZIP file, but we want to have the right to process diffs first, as that is simpler for us.

Please submit your solutions by Sat, Oct 4, 2008. Good luck, and do not forget to keep BackwardCompatibility!
