public class ConcurrentHashSet<E> extends AbstractSet<E> implements Set<E>, Cloneable, Serializable
| Constructor and Description |
|---|
ConcurrentHashSet()
Constructs a new, empty set; the backing ConcurrentHashMap instance has
default initial capacity (16) and load factor (0.75).
|
ConcurrentHashSet(Collection<? extends E> c)
Constructs a new set containing the elements in the specified
collection.
|
ConcurrentHashSet(int initialCapacity)
Constructs a new, empty set; the backing HashMap instance has
the specified initial capacity and default load factor, which is
0.75.
|
ConcurrentHashSet(int initialCapacity,
float loadFactor)
Constructs a new, empty set; the backing ConcurrentHashMap instance has
the specified initial capacity and the specified load factor.
