Method Detail

size

public int size()

Description copied from interface: Set

Returns the number of elements in this set (its cardinality). If this set contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Specified by:

size in interface Set

Specified by:

size in class AbstractCollection

Returns:

the number of elements in this collection.

isEmpty

public boolean isEmpty()

Description copied from interface: Set

Returns true if this set contains no elements.

Specified by:

isEmpty in interface Set

Overrides:

isEmpty in class AbstractCollection

Returns:

true if this collection contains no elements.

contains

public boolean contains(Object o)

Description copied from interface: Set

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 Set

Overrides:

contains in class AbstractCollection

Parameters:

o - object to be checked for containment in this collection.

Returns:

true if this collection contains the specified element.

remove

public boolean remove(Object o)

Description copied from interface: Set

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

Specified by:

remove in interface Set

Overrides:

remove in class AbstractCollection

Parameters:

o - element to be removed from this collection, if present.

Returns:

true if the collection contained the specified element.

iterator

public Iterator iterator()

Description copied from interface: Set

Returns an iterator over the elements in this set. The elements are returned in no particular order (unless this set is an instance of some class that provides a guarantee).

Specified by:

iterator in interface Set

Specified by:

iterator in class AbstractCollection

Returns:

an iterator over the elements contained in this collection.
