1. Create a class for pizzoa , add required attributes where one attribute is Manager_name. Write methods for add item, delete item, and display menu. Hint: you can use array list for menu items. 2. Create application class where you have to create an object of pizzoa class.
3. Assign manager name as your name from application class using object reference.
4. Write a code to display above mentioned menu in application class.
5. Take user input for desired choice of button and using conditional statements (if-else/switch case) call appropriate methods of pizzoa class.
6. On pressing 4 application program should stop running. Hint: use exit()
