* Interface that represents a collection of objects. This interface is the
* root of the collection hierarchy, and does not provide any guarantees about
* the order of its elements or whether or not duplicate elements are
* permitted.
* <p>
* All methods of this interface that are defined to modify the collection are
* defined as <dfn>optional</dfn>. An optional operation may throw an
* UnsupportedOperationException if the data backing this collection does not
* support such a modification. This may mean that the data structure is

* that it is modifiable but of fixed size (such as an array), or any number
* of other combinations.
* <p>
* A class that wishes to implement this interface should consider subclassing
* AbstractCollection, which provides basic implementations of most of the
* methods of this interface. Classes that are prepared to make guarantees
* about ordering or about absence of duplicate elements should consider
* implementing List or Set respectively, both of which are subinterfaces of
* Collection.
* <p>
* A general-purpose implementation of the Collection interface should in most
* cases provide at least two constructors: One which takes no arguments and
* creates an empty collection, and one which takes a Collection as an argument
* and returns a collection containing the same elements (that is, creates a
* copy of the argument using its own implementation).
