Introduction
The java.util.LinkedHashSet class is a Hash table and Linked list implementation of the Set interface, with predictable iteration order.Following are the important points about LinkedHashSet:
This class provides all of the optional Set operations, and permits null elements.
Class declaration
Following is the declaration for java.util.LinkedHashSet class:
public class LinkedHashSet<E>
extends HashSet<E>
implements Set<E>, Cloneable, Serializable
Parameters

Class constructors
| S.N. | Constructor & Description |
|---|---|
| 1 | LinkedHashSet() This constructs a new, empty linked hash set with the default initial capacity (16) and load factor (0.75). |
| 2 | LinkedHashSet(Collection<? extends E> c) This constructs a new linked hash set with the same elements as the specified collection. |
| 3 | LinkedHashSet(int initialCapacity) This constructs a new, empty linked hash set with the specified initial capacity and the default load factor (0.75). |
| 4 | LinkedHashSet(int initialCapacity, float loadFactor) This constructs a new, empty linked hash set with the specified initial capacity and load factor. |
