Swing 实现的Gui链表

https://gitee.com/dgwcode/MyJavaCode
-Freight类可以实现的功能
·构造方法：初始空车厢有5个
·装货：当运往某地点的货物大于等于4个的时候，如果有空车箱，则先占用整个空车厢，如果没有空车厢，则在尾部新增一个车厢节点，存放货物（假设不存在超过7个的情况），并且从链表头部依次搜索是否有车厢还有空位，如果有，将多出来的零散货物分别装进车厢（如上图的5件B，先装满第二个车厢，然后搜索后再将剩余的一件装入第一车厢）
·卸货：当到达某地时，以B为例，搜索链表，如果某个车厢都是该地货物，则从链表中删除此节点，并将其他零散B地货物从车厢中去除。
