Java implements XML file student address book

Java implements student address book, uses XML files as data storage, and implements the functions of adding, deleting, modifying, searching, backup, restoring, professional classification searching of student numbers, names, ages, address, majors, birthdays and other information.

The project needs to import the dom4j.jar package.
