java售票系统（涉及线程和xml）
来源：互联网 发布：ubuntu系统字体 编辑：程序博客网 时间：2024/06/08 11:34
构建售票场景演示。
（1）通过图形化界面实现功能；
（2）支持手动动态设置总票数（200以上），要对票本身进行定义和描述；
（3）程序运行时，设定有20个售票员同时售票，售票行为采用随机数实现，使多个售票员的售票时间彼此没有规律性；
（4）在程序运行过程中，伴随正在售票，要在用户界面上显示当前剩余票数，以及各售票员已经售出的票数；
（5）在所有票均售出后，要对各个售票员的售票情况进行总结（至少包括售票数量，各次出票时间，票面信息），并按其卖票数量进行排名；
（6）展示的售票情况结果要能够采用文件方式导出并保存在本地，并且支持对该文本的直接打开和查看；文件内容模板请同学们自行设计。推荐采用xml实现。
（7）售票员的个数和单个售票员参数（如ID，名字，…）的设置，要求采用文件导入方式进行配置，导入后，要在界面上显示导入的各个售票员信息；
（8）要保证程序的健壮性。
文件布局：
1.Seller类
implements Comparable 为后面买票人员排序
