RSS订阅原创 java.util.Stack类
/** * The <code>Stack</code> class represents a last-in-first-out * (LIFO) stack of objects. It extends class <tt>Vector</tt> with five * operations that allow a vector to be treated as a stack. The usual * <tt>push</tt

原创 java.util.Queue接口
/** * 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 t

原创 java.util.Deque接口
支持在两端插入和删除元素的线性集合。大多数Deque实现对它们可能包含的元素数量没有固定的限制， 但是此接口支持容量受限的双端队列以及没有固定大小限制的双端队列。 * 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 p.

原创 java.util.AbstractSequentialList抽象类
此类提供了List接口的基本实现，以最大程度地减少实现由“顺序访问”数据存储（例如链表）支持的该接口所需的工作。 对于随机访问数据（例如数组），应优先使用AbstractList来代替此类。 * This class provides a skeletal implementation of the <tt>List</tt> * interface to minimize the effort required to implement this interface *.

原创 java.util.ListIterator接口
* An iterator for lists that allows the programmer * to traverse the list in either direction, modify * the list during iteration, and obtain the iterator's * current position in the list. A {@code ListIterator} * has no current element; its <I>.

原创 java.util.ArrayDeque类
Deque接口的可调整大小的数组实现。 阵列双端队列没有容量限制。 它们会根据需要增长以支持使用。 它们不是线程安全的。 在没有外部同步的情况下，它们不支持多个线程的并发访问。 空元素是禁止的。 用作堆栈时，此类可能比Stack更快，而用作队列时，此类可能比LinkedList更快。 * Resizable-array implementation of the {@link Deque} interface. Array * deques have no capacity restrict.
