LinkedHashSet in Java | How to implement LinkedHashSet

LinkedHashSet has following Features:
- No Duplicate values
- Iteration order maintained
- Permits null value
- Implements Set Interface, extends HashSet Class
- Not Synchronized
- Underlying Data structure is HashTable & Doubly Linked List
- Internal Working is based on HashMap
- Initial Capacity
- Load Factor = Number of elements present / Size of HashTable
- Default initial capacity is 16 & load factor is 0.75
- LinkedHashSet h = new LinkedHashSet();
- LinkedHashSet h = new LinkedHashSet(int initialCapacity);
- LinkedHashSet h = new LinkedHashSet(int initialCapacity, float loadFactor);

Hi, to print the values of the LinkedHashSet you could use a for(val : linkedHashSet) Loop, it's a bit simpler.

Thanks for your videos. Given the fact that LinkedHashSet use DLL while HashSet doesn't use any LL, is there any performance hit in iterating a LinkedHashSet vs HashSet?

initial capacity of HashTable is 11 not 16
