Method Detail
-
iterator
public Iterator iterator()
Returns an iterator over the elements contained in this collection.- Specified by:
iterator
in interfaceCollection
- Specified by:
iterator
in interfaceIterable
- Specified by:
iterator
in interfaceSet
- Specified by:
iterator
in classAbstractCollection
- Returns:
- an iterator over the elements contained in this collection.
-
size
public int size()
Returns the number of elements in this collection. If the collection contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.- Specified by:
size
in interfaceCollection
- Specified by:

in interfaceSet
- Specified by:
size
in classAbstractCollection
- Returns:
- the number of elements in this collection.
-
contains
public boolean contains(Object o)
Returns true if this collection contains the specified element. More formally, returns true if and only if this collection contains at least one element e such that (o==null ? e==null : o.equals(e)).- Specified by:
contains
in interfaceCollection
- Specified by:
contains
in interfaceSet
- Overrides:
contains
in classAbstractCollection
- Parameters:
o
- object to be checked for containment in this collection- Returns:
- true if this collection contains the specified element
-
toArray
public Object[] toArray()
Returns an array containing all of the elements in this collection. If the collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. The returned array will be "safe" in that no references to it are maintained by the collection. (In other words, this method must allocate a new array even if the collection is backed by an Array). The caller is thus free to modify the returned array.- Specified by:
toArray
in interfaceCollection
- Specified by:
toArray
in interfaceSet
- Overrides:
toArray
in classAbstractCollection
- Returns:
- an array containing all of the elements in this collection
-
toArray
public Object[] toArray(Object[] aoDest)
Returns an array with a runtime type is that of the specified array and that contains all of the elements in this collection. If the collection fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this collection.If the collection fits in the specified array with room to spare (i.e. the array has more elements than the collection), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the collection only if the caller knows that the collection does not contain any null elements.)
- Specified by:
toArray
in interfaceCollection
- Specified by:
toArray
in interfaceSet
- Overrides:
toArray
in classAbstractCollection
- Parameters:
aoDest
- the array into which the elements of the collection are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose- Returns:
- an array containing the elements of the collection
- Throws:
ArrayStoreException
- if the runtime type of the specified array is not a supertype of the runtime type of every element in this collection
-
add
public boolean add(Object o)
Ensures that this collection contains the specified element (optional operation). Returns true if the collection changed as a result of the call. (Returns false if this collection does not permit duplicates and already contains the specified element.) Collections that support this operation may place limitations on what elements may be added to the collection. In particular, some collections will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. Collection classes should clearly specify in their documentation any restrictions on what elements may be added.- Specified by:
add
in interfaceCollection
- Specified by:
add
in interfaceSet
- Overrides:
add
in classAbstractCollection
- Parameters:
o
- element whose presence in this collection is to be ensured- Returns:
- true if the collection changed as a result of the call
- Throws:
ClassCastException
- if the class of the specified element prevents it from being added to this collection.
