Short tip: CollectionUtils class in Java

The link to the actual source pointed to the wrong source, but Julian made me aware of the problem. The link has been corrected. This utility class contains static methods that help managing collections (Vectors and arrays) in JDK 1.1.8. Well known @formulas like trim, unique and implode are some of the more interesting methods.

Apache Jakarta has a Commons component called Collections that has a huge amount of goodies!
