TreeSet is an implementation class of NavigableSet interface which is a child interface of SortedSet. It is a class in the collection framework that stores and manipulates elements in some sorting order. It represents self-balancing binary tree as its underlying data structure which makes it a good choice for search and retrieving operations. Syntax: Set<T> set = new TreeSet<T>(); It stores…

HashSet and TreeSet in Java

Both are present in java. util package. Both evaluate on the basis of object values, not on the basis of the index. Both cannot store any duplicate index.

HashSet is faster than TreeSet and it should be the preferred choice if sorting of the element is not required.

Difference:- HashSet store in random order whereas TreeSet store data in ascending order.

Elements in HashSet are not…

Java Collections: Differences between TreeSet, LinkedHashSet and HashSet

To effectively use Java Sets a Java programmer must understand the difference between TreeSet, LinkedHashSet and HashSet in Java. All three of them implement the Set interface and therefore don’t allow duplicate elements. Still, there are a few subtle differences in performance and usage patterns that every Java programmer must be aware of.
