Java实现 链表实现队列

链表实现队列类：

public class QueueLink {    public Node head;    private int size = 0;    public QueueLink() {        head = new Node();    }    public void inQueue(String name) {        Node q = head;        Node node = new Node(name);        while (q.next != null) {            q = q.next;        }        /**         * 队尾进入         */        q.next = node;        size ++;    }    public String outQueue() {        Node q = head;        String name = null;        if (q.next != null) {            name = q.next.name;            /**             * 删除队首的节点             * 将head next跳跃当前节点指向下个节点             */            q.next = q.next.next;            size --;        }        return name;    }    public void display() {        Node p = head;        while (p.next != null) {            p = p.next;            System.out.println(p.name);        }    }    public int size() {        return size;    }}

节点类不贴了，很简单，之前也都贴过，一样的。
