I am trying to get a code that takes a csv file and puts it into an ArrayList and shows the content of the ArrayList. I believe I have the code correct for getting the data into the ArrayList but I can't get it to print. Please any advice is welcome. I am very new to Java and coding in general.

import java.io.BufferedReader;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.IOException;

import java.util.ArrayList;



class Employee{

    public String FirstName;

    public String LastName;

    public String Company;

    public String Address;

    public String City;

    public String County;

    public String State;

    public String Zip;

    public String Phone;

    public String Fax;

    public String Email;

    public String Web;    

}       



public class JTeagueITCO321IPWeek4 {

    public static void main(String args) throws FileNotFoundException, IOException {



        String line = "";

        ArrayList <Employee> ALEmployee = new ArrayList();



        FileReader fr = new FileReader("C:\Users\User\Downloads\ITCO321_U4IP_sample_data.csv");

        try (BufferedReader br = new BufferedReader(fr)) {

            while ((line = br.readLine())!=null){ 

                Employee emp = new Employee();

                String empFields = line.split(",");

                emp.FirstName = empFields[0];

                emp.LastName = empFields[1];

                emp.Company = empFields[2];

                emp.Address = empFields[3];

                emp.City = empFields[4];

                emp.County = empFields[5];

                emp.State = empFields[6];

                emp.Zip = empFields[7];

                emp.Phone = empFields[8];

                emp.Fax = empFields[9];

                emp.Email = empFields[10];

                emp.Web = empFields[11];

                ALEmployee.add(emp);

            }

        }

    }

} 

To print an ArrayList you can just

• Use System.out.println(ALEmployee);



• 
  

  or be more precise and print each element one by one

  
  
  

  for(Employee e : ALEmployee){
  
      System.out.println(e);
  
  }
  
  

  
  

In both case you'll need to implement the toString() method in Employee class as :

public String toString(){

    return FirstName+" "+LastName+" "+Company; // do whatever you want here

}

Also I would suggest you, to follow Java conventions and coding conventions to:

• use lowerCamelCase for naming the attributs/variables


• set the attributs as private and use setters or a constructor to instanciate an Employee with its attributs
