WebTreeMap and TreeSet. TreeMap and TreeSet are basic Java collections added in Java 1.2. TreeMap is a mutable, ordered, Map implementation. Similarly, TreeSet is a mutable, ordered Set implementation. TreeMap is implemented as a Red-Black tree, which provides O (log n) access times. TreeSet is implemented using a TreeMap with dummy values. WebIf you want O(1) retrieval of the maximum, and you are allowed to change the type of collection being used, use a sorted set/map (e.g. TreeSet/TreeMap). You can use Collections.max(Collection) to find the maximum element out of any collection.
