Since TreeMaps are sorted by keys, the object for key has to be able to compare with each other, that's why it has to implement Comparable interface. For example, you use String as key, because String implements Comparable interface. Let's change the Dog, and make it comparable. classD...
(add,containsandremove), assuming the hash function disperses elements properly among the buckets. Performance is likely to be just slightly below that ofHashMap, due to the added expense of maintaining the linked list, with one exception: Iteration over the collection-views of aLinkedHashMap...
