The LinkedHashSet is an ordered version of HashSet that maintains a doubly-linked List across all elements. When the iteration order is needed to be maintained, this class is used. When iterating through a HashSet, the order is unpredictable, while a LinkedHashSet lets us iterate through the elements in the order in which they were inserted. When cycling through LinkedHashSet using an iterator, the elements will be returned to the order in which they were inserted.
To implement LinkedHashSet API first, we create a class “LinkedHashSetImplmentation” and create all the methods of the LinkedHashSet in this class.
Implementation of the LinkedHashMap API:
Size of the LinkedHashset: 5 The LinkedHashSet elements are: 10 20 30 40 50 The linkedHashSet is empty: false LinkedHashSet contains 60: false LinkedHashSet contains 40: true Size of the linkedHashSet:4 Size of the set after clear:0
