The name deque is short for \"double ended queue\"\n * and is usually pronounced \"deck\". Most Deque\n * implementations place no fixed limits on the number of elements\n * they may contain, but this interface supports capacity-restricted\n * deques as well as those with no fixed size limit.\n * This interface defines methods to access the elements at both\n * ends of the deque. Methods are provided to insert, remove, and\n * examine the element. Each of these methods exists in two forms:\n * one throws an exception if the operation fails, the other returns a\n * special value (either null or false, depending on\n * the operation). The latter form of the insert operation is\n * designed specifically for use with capacity-restricted\n * Deque implementations; in most implementations, insert\n * operations cannot fail.\n * The twelve methods described above are summarized in the\n * following table:\n * This interface extends the {@link Queue} interface. When a deque is\n * used as a queue, FIFO (First-In-First-Out) behavior results. Elements are\n * added at the end of the deque and removed from the beginning. The methods\n * inherited from the Queue interface are precisely equivalent to\n * Deque methods as indicated in the following table:\n * Deques can also be used as LIFO (Last-In-First-Out) stacks. This\n * interface should be used in preference to the legacy {@link Stack} class.\n * When a deque is used as a stack, elements are pushed and popped from the\n * beginning of the deque. Stack methods are precisely equivalent to\n * Deque methods as indicated in the table below:\n * Note that the {@link #peek peek} method works equally well when\n * a deque is used as a queue or a stack; in either case, elements are\n * drawn from the beginning of the deque.\n * This interface provides two methods to remove interior\n * elements, {@link #removeFirstOccurrence removeFirstOccurrence} and\n * {@link #removeLastOccurrence removeLastOccurrence}.\n * Unlike the {@link List} interface, this interface does not\n * provide support for indexed access to elements.\n * While Deque implementations are not strictly required\n * to prohibit the insertion of null elements, they are strongly\n * encouraged to do so. Users of any Deque implementations\n * that do allow null elements are strongly encouraged not to\n * take advantage of the ability to insert nulls. This is so because\n * null is used as a special return value by various methods\n * to indicated that the deque is empty.\n * Deque implementations generally do not define\n * element-based versions of the equals and hashCode\n * methods, but instead inherit the identity-based versions from class\n * Object.\n *\n * @param This method is equivalent to {@link #add}.\n *\n * @param e the element to add\n * @throws IllegalStateException if the element cannot be added at this\n * time due to capacity restrictions\n * @throws ClassCastException if the class of the specified element\n * prevents it from being added to this deque\n * @throws NullPointerException if the specified element is null and this\n * deque does not permit null elements\n * @throws IllegalArgumentException if some property of the specified\n * element prevents it from being added to this deque\n */\n void addLast(E e);\n\n /**\n * Inserts the specified element at the front of this deque unless it would\n * violate capacity restrictions.
