After knowing Hashtable vs HashMap, now let us see the comparison of HashMap with TreeMap. Basically both are derived from Map interface and meant to store key/value pairs. But TreeMap inherits one more interface SortedMap and for this reason it attains the property of returning the elements in sorting order by default (irrespective of the …
Two programs are given on TreeMap with the following operations. TreeMap General: The general operations like object creation, addition and deletion of key/value pairs, knowing the existence of a key or value or elements and size etc. are performed. TreeMap Special: The special operations like sorting the elements on key basis and value basis, adding …

TreeMap is derived from SortedMap interface and attains the property of printing the elements in ascending order. With Comparator, the order can be changed. The Comparator should be supplied at the time of TreeMap object creation itself. Methods of TreeMap are not synchronized and thereby not thread-safe. Using in multithreaded environment is not advisable. A …
As you can observe in the collections framework hierarchy, the Map interface comes with another sub interface SortedMap. The SortedMap can make use of all the methods of Map interface and also it adds its own (the list is given hereunder). The extra advantage (the original one is unique keys, a feature derived from its …
