数据结构中队列的java代码。实现了队列类的定义、队列的初始化、出队列的基本操作、入队列的基本操作、判断队列是否为空、判断队列的是否满、求取队列的长度、队列的清零与释放等功能。同时还详细定义了队列实现过程中元素节点的数据结构。节点数据的输入采用键盘输入，采用的是java.util.Scanner类中的方法。-Queue data structure java code. Implementation of the queue class definition, initialize the queue, the queue' s basic operations, into the basic operation of the queue, whether the queue is empty, it is judged whether the queue is full, the strike length of the queue, the queue is cleared and release functions. It also defines in detail the implementation process queue element node data structure. Node data input using keyboard input, using java.util.Scanner class method.
