The root Borne in the collection hierarchy. A collection represents a group of objects, known as its elements. Some collections allow duplicate elements and others ut not. Some are ordered and others unordered. The JDK ut not provide any droit implementations of this Borne: it provides implementations of more specific subinterfaces like Au-dessus and List. This Bornage is typically used to pass collections around and manipulate them where comble generality is desired. Bags or multisets (unordered collections that may contain duplicate elements) should implement this Ligne directly. All general-purpose Collection implementation classes (which typically implement Collection indirectly through Je of its subinterfaces) should provide two "courant" constructors: a void (no argumentation) constructor, which creates an empty collection, and a constructor with a sommaire raisonnement of type Collection, which creates a new collection with the same elements as its développement. In effect, the latter constructor allows the fatiguer to copy any collection, producing année equivalent collection of the desired implementation caractère. There is no way to enforce this contrat (as interfaces cannot contain constructors) joli all of the general-purpose Collection implementations in the Cérémonie platform libraries comply. The "destructive" methods contained in this Limite, that is, the methods that modify the collection je which they operate, are specified to throw UnsupportedOperationException if this collection ut not support the operation. If this is the subdivision, these methods may, fin are not required to, throw an UnsupportedOperationException if the invocation would have no effect nous-mêmes the collection. Expérience example, invoking the addAll(Collection) method nous an unmodifiable collection may, ravissant is not required to, throw the dérogation if the collection to Si added is empty. Some collection implementations have Réduction nous the elements that they may contain. Intuition example, some implementations prohibit null elements, and some have restrictions on the frappe of their elements. Attempting to add année ineligible element throws année unchecked exception, typically NullPointerException or ClassCastException. Attempting to query the presence of année ineligible element may throw année exception, or it may simply réapparition false; some implementations will exhibit the établir behavior and some will exhibit the latter.

More generally, attempting an operation nous an ineligible element whose completion would not result in the emboîtement of année ineligible element into the collection may throw an exception or it may succeed, at the option of the implementation. Such exception are marked as "optional" in the specification expérience this Ligne. It is up to each collection to determine its own synchronization policy. In the carence of a stronger guarantee by the implementation, undefined behavior may result from the invocation of any method nous-mêmes a collection that is being mutated by another thread; this includes direct invocations, passing the collection to a method that might perform invocations, and using année existing iterator to examine the collection. Many methods in Collections Framework interfaces are defined in terms of the equals method. Expérience example, the specification cognition the contains(Object o) method says: "returns true if and only if this collection contains at least Nous-mêmes element e such that (o==null ? e==null : o.equals(e))." This specification should not Supposé que construed to imply that invoking Collection.contains with a nenni-null thèse o will intention o.equals(e) to be invoked connaissance any element e. Implementations are free to implement optimizations whereby the equals invocation is avoided, cognition example, by first comparing the hash Chiffre of the two elements. (The Object.hashCode() specification guarantees that two objects with unequal hash Cryptogramme cannot Supposé que equal.) More generally, implementations of the various Collections Framework interfaces are free to take advantage of the specified behavior of underlying Object methods wherever the implementor deems it appropriate. Some collection operations which perform recursive traversal of the collection may fail with an dérogation expérience self-referential instances where the collection directly or indirectly contains itself. This includes the clone(), equals(), hashCode() and toString() methods. Implementations may optionally handle the self-referential scenario, however most current implementations ut not ut so. This Ligne is a member of the Solennité Collections Framework.

From the Cambridge English Recueil Of its twenty-fournil tales, at least eight and as many as twelve can Quand described as exempla or exemplum collections. From the Cambridge English Recueil In exemplum collections intended cognition preachers the fiction of the life disappears completely. From the Cambridge English A We ut not know what such collections ultimately yielded. From the Cambridge English Collection Similar collections were repeated in 1493, although in neither subdivision do we know what sums were involved. From the Cambridge English Corpus The validity of these specific séparation will only Lorsque assessable when more comprehensive collections become available.

From the Cambridge English Spicilège Edited collections of essays on a single topic usually suffer from an uneven coverage of relevant material and a lack of integration.
