Phone,type,area code,prefix,suffix
(3) the class must be able to read a file (ask the user for the name of the file) and somehow return an ArrayList. This ArrayList can then be passed to your Database class and used with the methods there.The I/O class must also be able to take your ArrayList of Person objects and write all of the data to a NEW output file.
4.ystem to your database program which allows the user to test all functionality from the first program, i.e. menu options for all the things you were supposed to test in Homework 05. In addition to being able to save / load information to / from a chosen input file and chosen output file. Add an option to also be able to create a new person for the database. The person could be any of the person types from the previous assignment. This new person should be added to the ArrayList of people.
The requirement is that I have to (1) have a menu system method in database class for the user
2have a class that provides a way to read and write data from / to a file and populate an ArrayList of Person objects or save the data of an ArrayList of objects. Build a new class which uses Text I/O to read text from a .csv (ObjectType,first-name,last-name, . all the rest of the information
Can someone check the code that I have so far, homework 5 is basically creating the database system that has several classes inheriting from the main Person class, and it will count how many people are in the system and how many students/how many staff/how many employees etc. and this assignment is an add up to hmk 5, so far I have the code as below. I am stuck on creating the menu to let user create the new person and store it to the arraylist so that it can access the methods in database class, and also the reading of the file, I always got an IndexOutofBound exception and I dont know how to solve it..

I know this is a lot but I am totally stuck on this assignment, please help.
Overview: For this program you will be adding a new class to Homework 05. This class will provide a way to read and write data from / to a file and populate an ArrayList of Person objects or save the data of an ArrayList of objects. Build a new class which uses Text I/O to read text from a.csv (comma separated value) file. The text file will have values in the following format: ObjectType,first-name, 1ast-name, all the rest of the information Phone, type, area code,prefix, suffix A person could have any number of phone numbers listed after their information. There are no spaces between the entries, and no spaces before or after a comma. I am leaving this assignment fairly vague because I want you to design the class in your own way. The only requirement is that the class must be able to read a file (ask the user for the name of the file) and somehow return an ArrayList. This ArrayList can then be passed to your Database class and used with the methods there. The I/O class must also be able to take your ArrayList of Person objects and write all of the data to a NEW output file.
