This is a small collection of algorithms and data structures implemented 'Effective Java' style (in reference to the masterpiece writted by Joshua Bloch : Effective Java (2nd Edition). The algorithms were implemented quite a while ago and are there mostly for educational purposes. You can also reference a general checklist which was used to follow the principles outlined in the book in the effective-checklist folder.
A newer edition of the book is available and you can find it here: Effective Java (3rd Edition).
