GoKawiilNew open-source Java library ChaosTree offers AVL, Red-Black, B-Tree and B+ Tree structures
A developer released ChaosTree, a zero-dependency Java library implementing multiple sorted-tree data structures—AVL, Red-Black, B-Tree, and B+ Tree—with Set and Map APIs modeled on JDK's NavigableSet, NavigableMap, SequencedSet, and SequencedMap interfaces. It also includes specialized bulk-construction methods like buildFromSorted and importFlatMatrix that let developers tune node occupancy directly.
