Java Programming (14.3)-----Library Management System Preliminary Design interface page ~ Library directory view window, new book Add window

1. In-place instantiation, table, table scroll bar, scroll bar automatically appear, table Model 2. New window, upper and lower adjustment of the input box, the data acquisition method in the input box, the input box assembly settings, reset the input box contents

Note that a bookmanager is common with the main window ... In the beginning because of this window new a manager kill add not to go in ... You won't get an error ....

1 Code first the main window can show all the library buttons 2 additions and deletions are only made to the new
