Constructor Detail

HashSetNotSync

public HashSetNotSync()
Constructs a new, empty set; the backing HashMap instance has default initial capacity (16) and load factor (0.75).

Method Detail

iterator

public Iterator iterator()
Returns an iterator over the elements in this set. The elements are returned in no particular order.

Specified by:
iterator in interface Iterable
Specified by:
iterator in interface Collection
Specified by:
iterator in interface Set
Specified by:
iterator in class AbstractCollection
Returns:
an Iterator over the elements in this set

ConcurrentModificationException

size

public int size()
Returns the number of elements in this set (its cardinality).

Specified by:
size in interface Collection
Specified by:
size in interface Set
Specified by:
size in class AbstractCollection
Returns:
the number of elements in this set (its cardinality)

isEmpty

public boolean isEmpty()
Returns true if this set contains no elements.

Specified by:
isEmpty in interface Collection
Specified by:
isEmpty in interface Set
Overrides:
isEmpty in class AbstractCollection
Returns:
true if this set contains no elements

contains

public boolean contains(Object o)
Returns true if this set contains the specified element. More formally, returns true if and only if this set contains an element e such that (o==null ? e==null : o.equals(e)).

Specified by:
contains in interface Collection
Specified by:
contains in interface Set
Overrides:
contains in class AbstractCollection
Parameters:
o - element whose presence in this set is to be tested
Returns:
true if this set contains the specified element

add

public boolean add(Object e)
Adds the specified element to this set if it is not already present. More formally, adds the specified element e to this set if this set contains no element e2 such that (e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returns false.

Specified by:
add in interface Collection
Specified by:
add in interface Set
Overrides:
add in class AbstractCollection
Parameters:
e - element to be added to this set
Returns:
true if this set did not already contain the specified element

remove

public boolean remove(Object o)
Removes the specified element from this set if it is present. More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if this set contains such an element. Returns true if this set contained the element (or equivalently, if this set changed as a result of the call). (This set will not contain the element once the call returns.)

Specified by:
remove in interface Collection
Specified by:
remove in interface Set
Overrides:
remove in class AbstractCollection
Parameters:
o - object to be removed from this set, if present
Returns:
true if the set contained the specified element

clear

public void clear()
Removes all of the elements from this set. The set will be empty after this call returns.

Specified by:
clear in interface Collection
Specified by:
clear in interface Set
Overrides:
clear in class AbstractCollection

clone

public Object clone()
Returns a shallow copy of this HashSet instance: the elements themselves are not cloned.

Overrides:
clone in class Object
Returns:
a shallow copy of this set
