Question

The Final project will be a system to store data related to student members of a club. The program will read and write a file. The file will be read and stored into an array or ArrayList when the program starts and re-written when the program is exited. The file should store info about the student: number (the first student is 1 then each additional student is the next number), name, and email.

The program should allow the user to add a member, edit a member, delete a member, and list all members.

The following menus should be as follows:
