Java Bean实现航空预定机票功能应用‖

预定构件功能说明：

1，预定构件应包含二个面板，预定座位面板与乘客面板

2，在装入预定构件时不应有可用的乘客面板

3，当用户打入要预定的旅行地点.旅行日期及座位号时：

(1)首先，应按以下格式生成乘客号：

(2)其次，在显示 中bean大小，以观看此乘客

乘客号时应使乘客面板是可见的 面板。而且，如果打入座位号为

（注意：你可能重定BeanBox窗口 0，则不应显示乘客面板。）

(3)当用户点击乘

客面板的submit按钮时，此面板

的所有域控件中文本应置为空

(4)上面步骤被重复，直到所接收的乘客材料个数等于预定的座位数为止

4，在已预定了所需座位号之后，给出所预定座位号的消息框应被显示d

5,乘客面板应作为bean创建，可以把嵌入在铁路预定应用或航空应用中

6，你需接受以下格式

之一的旅行日期"dd/mm/yy","mm

/dd/yy","dd-Month-yy"
