/**
* The root interface in the <i>collection hierarchy</i>. A collection
* represents a group of objects, known as its <i>elements</i>. Some
* collections allow duplicate elements and others do not. Some are ordered
* and others unordered. The JDK does not provide any <i>direct</i>
* implementations of this interface: it provides implementations of more
* specific subinterfaces like <tt>Set</tt> and <tt>List</tt>. This interface
* is typically used to pass collections around and manipulate them where
* maximum generality is desired.
*
* <p><i>Bags</i> or <i>multisets</i> (unordered collections that may contain
* duplicate elements) should implement this interface directly.
*
* <p>All general-purpose <tt>Collection</tt> implementation classes (which
* typically implement <tt>Collection</tt> indirectly through one of its
* subinterfaces) should provide two "standard" constructors: a void (no
* arguments) constructor, which creates an empty collection, and a
* constructor with a single argument of type <tt>Collection</tt>, which
* creates a new collection with the same elements as its argument. In
* effect, the latter constructor allows the user to copy any collection,
* producing an equivalent collection of the desired implementation type.
* There is no way to enforce this convention (as interfaces cannot contain
* constructors) but all of the general-purpose <tt>Collection</tt>
* implementations in the Java platform libraries comply.
*
* <p>The "destructive" methods contained in this interface, that is, the
* methods that modify the collection on which they operate, are specified to
* throw <tt>UnsupportedOperationException</tt> if this collection does not
* support the operation. If this is the case, these methods may, but are not
* required to, throw an <tt>UnsupportedOperationException</tt> if the
* invocation would have no effect on the collection. For example, invoking
* the {@link #addAll(Collection)} method on an unmodifiable collection may,
* but is not required to, throw the exception if the collection to be added
* is empty.
*
* <p>Some collection implementations have restrictions on the elements that
* they may contain. For example, some implementations prohibit null elements,
* and some have restrictions on the types of their elements. Attempting to
* add an ineligible element throws an unchecked exception, typically
* <tt>NullPointerException</tt> or <tt>ClassCastException</tt>. Attempting
* to query the presence of an ineligible element may throw an exception,
* or it may simply return false; some implementations will exhibit the former
* behavior and some will exhibit the latter. More generally, attempting an
* operation on an ineligible element whose completion would not result in
* the insertion of an ineligible element into the collection may throw an
* exception or it may succeed, at the option of the implementation.
* Such exceptions are marked as "optional" in the specification for this
* interface.
*
* <p>It is up to each collection to determine its own synchronization
* policy. In the absence of a stronger guarantee by the
* implementation, undefined behavior may result from the invocation
* of any method on 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 an existing
* iterator to examine the collection.
*
* <p>Many methods in Collections Framework interfaces are defined in
* terms of the {@link Object#equals(Object) equals} method. For example,
* the specification for the {@link #contains(Object) contains(Object o)}
* method says: "returns <tt>true</tt> if and only if this collection
* contains at least one element <tt>e</tt> such that
* <tt>(o==null ? e==null : o.equals(e))</tt>." This specification should
* <i>not</i> be construed to imply that invoking <tt>Collection.contains</tt>
* with a non-null argument <tt>o</tt> will cause <tt>o.equals(e)</tt> to be
* invoked for any element <tt>e</tt>. Implementations are free to implement
* optimizations whereby the <tt>equals</tt> invocation is avoided, for
* example, by first comparing the hash codes of the two elements. (The
* {@link Object#hashCode()} specification guarantees that two objects with
* unequal hash codes cannot be equal.) More generally, implementations of
* the various Collections Framework interfaces are free to take advantage of
* the specified behavior of underlying {@link Object} methods wherever the
* implementor deems it appropriate.

/**
* This exception may be thrown by methods that have detected concurrent
* modification of an object when such modification is not permissible.
* <p>
* For example, it is not generally permissible for one thread to modify a Collection
* while another thread is iterating over it. In general, the results of the
* iteration are undefined under these circumstances. Some Iterator
* implementations (including those of all the general purpose collection implementations
* provided by the JRE) may choose to throw this exception if this behavior is
* detected. Iterators that do this are known as <i>fail-fast</i> iterators,
* as they fail quickly and cleanly, rather that risking arbitrary,
* non-deterministic behavior at an undetermined time in the future.
* <p>
* Note that this exception does not always indicate that an object has
* been concurrently modified by a <i>different</i> thread. If a single
* thread issues a sequence of method invocations that violates the
* contract of an object, the object may throw this exception. For
* example, if a thread modifies a collection directly while it is
* iterating over the collection with a fail-fast iterator, the iterator
* will throw this exception.
*
* <p>Note that fail-fast behavior cannot be guaranteed as it is, generally
* speaking, impossible to make any hard guarantees in the presence of
* unsynchronized concurrent modification. Fail-fast operations
* throw <tt>ConcurrentModificationException</tt> on a best-effort basis.
* Therefore, it would be wrong to write a program that depended on this

/**
* A linear collection that supports element insertion and removal at
* both ends. The name <i>deque</i> is short for "double ended queue"
* and is usually pronounced "deck". Most <tt>Deque</tt>
* implementations place no fixed limits on the number of elements
* they may contain, but this interface supports capacity-restricted
* deques as well as those with no fixed size limit.
*
* <p>This interface defines methods to access the elements at both
* ends of the deque. Methods are provided to insert, remove, and
* examine the element. Each of these methods exists in two forms:
* one throws an exception if the operation fails, the other returns a
* special value (either <tt>null</tt> or <tt>false</tt>, depending on
* the operation). The latter form of the insert operation is
* designed specifically for use with capacity-restricted
* <tt>Deque</tt> implementations; in most implementations, insert
* operations cannot fail.
*
* <p>The twelve methods described above are summarized in the
* following table:
*
* <p>
* <table BORDER CELLPADDING=3 CELLSPACING=1>
* <tr>
* <td></td>
* <td ALIGN=CENTER COLSPAN = 2> <b>First Element (Head)</b></td>
* <td ALIGN=CENTER COLSPAN = 2> <b>Last Element (Tail)</b></td>
* </tr>
* <tr>
* <td></td>
* <td ALIGN=CENTER><em>Throws exception</em></td>
* <td ALIGN=CENTER><em>Special value</em></td>
* <td ALIGN=CENTER><em>Throws exception</em></td>
* <td ALIGN=CENTER><em>Special value</em></td>
* </tr>
* <tr>
* <td><b>Insert</b></td>
* <td>{@link #addFirst addFirst(e)}</td>
* <td>{@link #offerFirst offerFirst(e)}</td>
* <td>{@link #addLast addLast(e)}</td>
* <td>{@link #offerLast offerLast(e)}</td>
* </tr>
* <tr>
* <td><b>Remove</b></td>
* <td>{@link #removeFirst removeFirst()}</td>
* <td>{@link #pollFirst pollFirst()}</td>
* <td>{@link #removeLast removeLast()}</td>
* <td>{@link #pollLast pollLast()}</td>
* </tr>
* <tr>
* <td><b>Examine</b></td>
* <td>{@link #getFirst getFirst()}</td>
* <td>{@link #peekFirst peekFirst()}</td>
* <td>{@link #getLast getLast()}</td>
* <td>{@link #peekLast peekLast()}</td>
* </tr>
* </table>
*
* <p>This interface extends the {@link Queue} interface. When a deque is
* used as a queue, FIFO (First-In-First-Out) behavior results. Elements are
* added at the end of the deque and removed from the beginning. The methods
* inherited from the <tt>Queue</tt> interface are precisely equivalent to
* <tt>Deque</tt> methods as indicated in the following table:
*
* <p>
* <table BORDER CELLPADDING=3 CELLSPACING=1>
* <tr>
* <td ALIGN=CENTER> <b><tt>Queue</tt> Method</b></td>
* <td ALIGN=CENTER> <b>Equivalent <tt>Deque</tt> Method</b></td>
* </tr>
* <tr>
* <td>{@link java.util.Queue#add add(e)}</td>
* <td>{@link #addLast addLast(e)}</td>
* </tr>
* <tr>
* <td>{@link java.util.Queue#offer offer(e)}</td>
* <td>{@link #offerLast offerLast(e)}</td>
* </tr>
* <tr>
* <td>{@link java.util.Queue#remove remove()}</td>
* <td>{@link #removeFirst removeFirst()}</td>
* </tr>
* <tr>
* <td>{@link java.util.Queue#poll poll()}</td>
* <td>{@link #pollFirst pollFirst()}</td>
* </tr>
* <tr>
* <td>{@link java.util.Queue#element element()}</td>
* <td>{@link #getFirst getFirst()}</td>
* </tr>
* <tr>
* <td>{@link java.util.Queue#peek peek()}</td>
* <td>{@link #peek peekFirst()}</td>
* </tr>
* </table>
*
* <p>Deques can also be used as LIFO (Last-In-First-Out) stacks. This
* interface should be used in preference to the legacy {@link Stack} class.
* When a deque is used as a stack, elements are pushed and popped from the
* beginning of the deque. Stack methods are precisely equivalent to
* <tt>Deque</tt> methods as indicated in the table below:
*
* <p>
* <table BORDER CELLPADDING=3 CELLSPACING=1>
* <tr>
* <td ALIGN=CENTER> <b>Stack Method</b></td>
* <td ALIGN=CENTER> <b>Equivalent <tt>Deque</tt> Method</b></td>
* </tr>
* <tr>
* <td>{@link #push push(e)}</td>
* <td>{@link #addFirst addFirst(e)}</td>
* </tr>
* <tr>
* <td>{@link #pop pop()}</td>
* <td>{@link #removeFirst removeFirst()}</td>
* </tr>
* <tr>
* <td>{@link #peek peek()}</td>
* <td>{@link #peekFirst peekFirst()}</td>
* </tr>
* </table>
*
* <p>Note that the {@link #peek peek} method works equally well when
* a deque is used as a queue or a stack; in either case, elements are
* drawn from the beginning of the deque.
*
* <p>This interface provides two methods to remove interior
* elements, {@link #removeFirstOccurrence removeFirstOccurrence} and
* {@link #removeLastOccurrence removeLastOccurrence}.
*
* <p>Unlike the {@link List} interface, this interface does not
* provide support for indexed access to elements.
*
* <p>While <tt>Deque</tt> implementations are not strictly required
* to prohibit the insertion of null elements, they are strongly
* encouraged to do so. Users of any <tt>Deque</tt> implementations
* that do allow null elements are strongly encouraged <i>not</i> to
* take advantage of the ability to insert nulls. This is so because
* <tt>null</tt> is used as a special return value by various methods
* to indicated that the deque is empty.
*
* <p><tt>Deque</tt> implementations generally do not define
* element-based versions of the <tt>equals</tt> and <tt>hashCode</tt>
* methods, but instead inherit the identity-based versions from class
* <tt>Object</tt>.
*

/**
* Linked list implementation of the <tt>List</tt> interface. Implements all
* optional list operations, and permits all elements (including
* <tt>null</tt>). In addition to implementing the <tt>List</tt> interface,
* the <tt>LinkedList</tt> class provides uniformly named methods to
* <tt>get</tt>, <tt>remove</tt> and <tt>insert</tt> an element at the
* beginning and end of the list. These operations allow linked lists to be
* used as a stack, {@linkplain Queue queue}, or {@linkplain Deque
* double-ended queue}. <p>
*
* The class implements the <tt>Deque</tt> interface, providing
* first-in-first-out queue operations for <tt>add</tt>,
* <tt>poll</tt>, along with other stack and deque operations.<p>
*
* All of the operations perform as could be expected for a doubly-linked
* list. Operations that index into the list will traverse the list from
* the beginning or the end, whichever is closer to the specified index.<p>
*
* <p><strong>Note that this implementation is not synchronized.</strong>
* If multiple threads access a linked list concurrently, and at least
* one of the threads modifies the list structurally, it <i>must</i> be
* synchronized externally. (A structural modification is any operation
* that adds or deletes one or more elements; merely setting the value of
* an element is not a structural modification.) This is typically
* accomplished by synchronizing on some object that naturally
* encapsulates the list.
*
* If no such object exists, the list should be "wrapped" using the
* {@link Collections#synchronizedList Collections.synchronizedList}
* method. This is best done at creation time, to prevent accidental
* unsynchronized access to the list:<pre>
* List list = Collections.synchronizedList(new LinkedList(...));</pre>
*
* <p>The iterators returned by this class's <tt>iterator</tt> and
* <tt>listIterator</tt> methods are <i>fail-fast</i>: if the list is
* structurally modified at any time after the iterator is created, in
* any way except through the Iterator's own <tt>remove</tt> or
* <tt>add</tt> methods, the iterator will throw a {@link
* ConcurrentModificationException}. Thus, in the face of concurrent
* modification, the iterator fails quickly and cleanly, rather than
* risking arbitrary, non-deterministic behavior at an undetermined
* time in the future.
*
* <p>Note that the fail-fast behavior of an iterator cannot be guaranteed
* as it is, generally speaking, impossible to make any hard guarantees in the
* presence of unsynchronized concurrent modification. Fail-fast iterators
* throw <tt>ConcurrentModificationException</tt> on a best-effort basis.
* Therefore, it would be wrong to write a program that depended on this
* exception for its correctness: <i>the fail-fast behavior of iterators
* should be used only to detect bugs.</i>

/**
* An ordered collection (also known as a <i>sequence</i>). The user of this
* interface has precise control over where in the list each element is
* inserted. The user can access elements by their integer index (position in
* the list), and search for elements in the list.<p>
*
* Unlike sets, lists typically allow duplicate elements. More formally,
* lists typically allow pairs of elements <tt>e1</tt> and <tt>e2</tt>
* such that <tt>e1.equals(e2)</tt>, and they typically allow multiple
* null elements if they allow null elements at all. It is not inconceivable
* that someone might wish to implement a list that prohibits duplicates, by
* throwing runtime exceptions when the user attempts to insert them, but we
* expect this usage to be rare.<p>
*
* The <tt>List</tt> interface places additional stipulations, beyond those
* specified in the <tt>Collection</tt> interface, on the contracts of the
* <tt>iterator</tt>, <tt>add</tt>, <tt>remove</tt>, <tt>equals</tt>, and
* <tt>hashCode</tt> methods. Declarations for other inherited methods are
* also included here for convenience.<p>
*
* The <tt>List</tt> interface provides four methods for positional (indexed)
* access to list elements. Lists (like Java arrays) are zero based. Note
* that these operations may execute in time proportional to the index value
* for some implementations (the <tt>LinkedList</tt> class, for
* example). Thus, iterating over the elements in a list is typically
* preferable to indexing through it if the caller does not know the
* implementation.<p>
*
* The <tt>List</tt> interface provides a special iterator, called a
* <tt>ListIterator</tt>, that allows element insertion and replacement, and
* bidirectional access in addition to the normal operations that the
* <tt>Iterator</tt> interface provides. A method is provided to obtain a
* list iterator that starts at a specified position in the list.<p>
*
* The <tt>List</tt> interface provides two methods to search for a specified
* object. From a performance standpoint, these methods should be used with
* caution. In many implementations they will perform costly linear
* searches.<p>
*
* The <tt>List</tt> interface provides two methods to efficiently insert and
* remove multiple elements at an arbitrary point in the list.<p>
*
* Note: While it is permissible for lists to contain themselves as elements,
* extreme caution is advised: the <tt>equals</tt> and <tt>hashCode</tt>
* methods are no longer well defined on such a list.
*
* <p>Some list implementations have restrictions on the elements that
* they may contain. For example, some implementations prohibit null elements,
* and some have restrictions on the types of their elements. Attempting to
* add an ineligible element throws an unchecked exception, typically
* <tt>NullPointerException</tt> or <tt>ClassCastException</tt>. Attempting
* to query the presence of an ineligible element may throw an exception,
* or it may simply return false; some implementations will exhibit the former
* behavior and some will exhibit the latter. More generally, attempting an
* operation on an ineligible element whose completion would not result in
* the insertion of an ineligible element into the list may throw an
* exception or it may succeed, at the option of the implementation.
* Such exceptions are marked as "optional" in the specification for this
* interface.

/**
* A collection designed for holding elements prior to processing.
* Besides basic {@link java.util.Collection Collection} operations,
* queues provide additional insertion, extraction, and inspection
* operations. Each of these methods exists in two forms: one throws
* an exception if the operation fails, the other returns a special
* value (either <tt>null</tt> or <tt>false</tt>, depending on the
* operation). The latter form of the insert operation is designed
* specifically for use with capacity-restricted <tt>Queue</tt>
* implementations; in most implementations, insert operations cannot
* fail.
*
* <p>
* <table BORDER CELLPADDING=3 CELLSPACING=1>
* <tr>
* <td></td>
* <td ALIGN=CENTER><em>Throws exception</em></td>
* <td ALIGN=CENTER><em>Returns special value</em></td>
* </tr>
* <tr>
* <td><b>Insert</b></td>
* <td>{@link #add add(e)}</td>
* <td>{@link #offer offer(e)}</td>
* </tr>
* <tr>
* <td><b>Remove</b></td>
* <td>{@link #remove remove()}</td>
* <td>{@link #poll poll()}</td>
* </tr>
* <tr>
* <td><b>Examine</b></td>
* <td>{@link #element element()}</td>
* <td>{@link #peek peek()}</td>
* </tr>
* </table>
*
* <p>Queues typically, but do not necessarily, order elements in a
* FIFO (first-in-first-out) manner. Among the exceptions are
* priority queues, which order elements according to a supplied
* comparator, or the elements' natural ordering, and LIFO queues (or
* stacks) which order the elements LIFO (last-in-first-out).
* Whatever the ordering used, the <em>head</em> of the queue is that
* element which would be removed by a call to {@link #remove() } or
* {@link #poll()}. In a FIFO queue, all new elements are inserted at
* the <em> tail</em> of the queue. Other kinds of queues may use
* different placement rules. Every <tt>Queue</tt> implementation
* must specify its ordering properties.
*
* <p>The {@link #offer offer} method inserts an element if possible,
* otherwise returning <tt>false</tt>. This differs from the {@link
* java.util.Collection#add Collection.add} method, which can fail to
* add an element only by throwing an unchecked exception. The
* <tt>offer</tt> method is designed for use when failure is a normal,
* rather than exceptional occurrence, for example, in fixed-capacity
* (or "bounded") queues.
*
* <p>The {@link #remove()} and {@link #poll()} methods remove and
* return the head of the queue.
* Exactly which element is removed from the queue is a
* function of the queue's ordering policy, which differs from
* implementation to implementation. The <tt>remove()</tt> and
* <tt>poll()</tt> methods differ only in their behavior when the
* queue is empty: the <tt>remove()</tt> method throws an exception,
* while the <tt>poll()</tt> method returns <tt>null</tt>.
*
* <p>The {@link #element()} and {@link #peek()} methods return, but do
* not remove, the head of the queue.
*
* <p>The <tt>Queue</tt> interface does not define the <i>blocking queue
* methods</i>, which are common in concurrent programming. These methods,
* which wait for elements to appear or for space to become available, are
* defined in the {@link java.util.concurrent.BlockingQueue} interface, which
* extends this interface.
*
* <p><tt>Queue</tt> implementations generally do not allow insertion
* of <tt>null</tt> elements, although some implementations, such as
* {@link LinkedList}, do not prohibit insertion of <tt>null</tt>.
* Even in the implementations that permit it, <tt>null</tt> should
* not be inserted into a <tt>Queue</tt>, as <tt>null</tt> is also
* used as a special return value by the <tt>poll</tt> method to
* indicate that the queue contains no elements.
*
* <p><tt>Queue</tt> implementations generally do not define
* element-based versions of methods <tt>equals</tt> and
* <tt>hashCode</tt> but instead inherit the identity based versions
* from class <tt>Object</tt>, because element-based equality is not
* always well-defined for queues with the same elements but different
* ordering properties.

*
* <p>The best algorithms for manipulating random access lists (such as

* sequential access lists (such as <tt>LinkedList</tt>). Generic list
* algorithms are encouraged to check whether the given list is an

*
* <p>It is recognized that the distinction between random and sequential
* access is often fuzzy. For example, some <tt>List</tt> implementations
* provide asymptotically linear access times if they get huge, but constant
* access times in practice. Such a <tt>List</tt> implementation
