http://issues.apache.org/bugzilla/show_bug.cgi?id=31444 New CollectionUtils feature and tests: chooseRandomElement from collection Summary: New CollectionUtils feature and tests: chooseRandomElement from collection Product: Commons Version: unspecified Platform: All OS/Version: Other Status: NEW Severity: Enhancement Priority: Other Component: Collections AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I find myself needing to do this every so often, but there's no Java collections or Commons Collections functionality. CollectionUtils seemed like a good place for something like this to rest. I will attach the Java source for CollectionUtils.java from CVS around 6:30pm PDT complete with the new functions (there are two, plus a new static data member). Also, I will attach the source for TestCollectionUtils.java which includes tests for this new functionality. The new code is at the end of each class. The function takes any collection, but is smart enough to use List's get() method if the collection is a list, resulting in constant time (or at least, much faster) behavior on classes which implement RandomAccess. Otherwise, the function simply picks a random index and linearly iterates to it, resulting in linear time complexity. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
