Overview: This is an example of two Java Bean applications that achieve the function of aviation reservation ticket.
Predetermined component function description:
1. The predetermined component should contain two panels, scheduled seating panels and passenger panels
2, should not have available passenger panels when loading a predetermined component
3. When the user is hits the travel location to be scheduled. Travel date and seat number:
(1) First, the passenger number should be generated in the following format:
(2) Second, the passenger panel should be visible when the passenger number is displayed (Note: You may refine the Bean size in the Beanbox window to watch this passenger panel. Moreover, if the seat number is 0, the passenger should not be displayed. panel.)
(3) When the user clicks the Submit button of the passenger panel, all domain controls in this panel should be empty
(4) The above steps are repeated until the received passenger material is equal to the predetermined number of seats.
4. After the desired seat number has been predetermined, the message box for the predetermined seat number should be displayed D.
5, the passenger panel should be created as bean, which can be embedded in the railway scheduled application or aviation application.
6, you need to accept one of the following formats "DD / MM / YY", "MM / DD / YY", "DD-MONTH-YY"
