I'm stuck at when user put information how to go back to menu and
I want to create super class for teacher and get do it...

any ideas or help is awesome! thank you guys!

Answer 1

You could start by cleaning up the code you have. Refactor into multiple methods so your code is more readable. For instance, take the code that displays the menu and put it into a method called displayMenu() and call that from main instead of having all your code in main. Often breaking your code up into chunks like this will help your thought process.

Menu, Student and Teacher could be there own classes. Student and Teacher might derive from (extend) another (abstract) class like Person or Human etc. You could also have a class that just handles displaying information. Your data handling should be separate from your other classes. If you need persistent data like a database or storing info in a file there should be a class that handles that.

Options 1-6 look like they should be methods in the Student and Teacher Classes.

You should loop until 0 is entered to exit.

main should be something clean and simple like

displayMenu();
int x = getInput();
handleInput(x);

Answer 2

Thank you! so I have 5 classes
1. main
2.displaymenu
3. human
4. student
5.teacher
but what should be in human class since option1-6 should be in the student and teacher classes?

my main is
displayMenu menu = new displayMenu();
menu.displaymenu();
now
