In this tutorial, we will learn about TreeSet in Java and how to use it. TreeSet extends AbstractSet class and implements the NavigableSet interface. The objects of the TreeSet class are stored in ascending order and uses a tree for storage. It further extends the Set Interface due to which it holds only unique objects. Some points …

SortedSet interface in Java is present in java.util package and extends Set Interface, which represents a set of unique objects also adds a feature that stores all the elements in a sorted manner. Set interface in Java is a subtype of the …
In this tutorial, we will learn about LinkedHashSet in Java and how to use it. As the name suggests “LinkedHashSet”, all elements are linked to each other by a doubly-linked list and also maintains order. Also, you can say it is an ordered version of HashSet. LinkedHashSet extends HashSet Class and implements the Set interface. Some points …
In this tutorial, we will learn about HashSet in Java and how to use it. HashSet implements Set Interface and it is backed by a HashMap.
