TreeSet in Java

What is a TreeSet? Implements Set interface It is more like a HashSet which contains unique elements but in a sorted ascending order Elements are comparable by a default/custom comparator Access & retrieval times are quite fast Initialized with a default capacity of 16 & 0.75 load factor TreeSet Contructors TreeSet() : Contructs an empty tree that will be sorted based on natual order of elements TreeSet(Collection c) : Builds a TreeSet from elements of collection c TreeSet(Compatator c) : Constructs an empty tree that will be sorted on given comparator TreeSet(SortedSet s) : Constructs from given SortedSet The elements in TreeSet must be of Comparable type String & Wrapper classes are Comparable by default To add user-defined objects, we need to implement Comparable interface As per Oracle, TreeSet provides log(n) cost time for basic add/remove/contains operation. While HashSet provide constant O(1) time performance
