WebJava Map implementation usually acts as a bucketed hash table. When buckets get too large, they get transformed into nodes of TreeNodes, each structured similarly to those in java.util.TreeMap. HashMap. HashMap implements Map, Cloneable and Serializable interface. It extends AbstractMap class. It belongs to java.util package. WebIf not, then I would suggest adding the Java-version these performances were measured at. I presume by and large the performance does not change dramatically though. I highly doubt this was measured. It's probably inferred from the implementation. And I doubt the complexity of the implementations changed.
