I'm almost done with this. Now, when I choose to display the contacts, I'm getting . I believe it's picking the right contact, just not showing me what I want to see. I'm guessing there's some method or something small that I'm missing. Any help would be appreciated.

Main:

package contactslist;
import java.util.*;
import java.io.*;
public class ContactsList {
    public static void main(String[] args) {
        Scanner input1 = new Scanner(System.in);
        int type = 0;
        ArrayList<Contacts> contacts = new ArrayList<Contacts>();
        int conID = 0;
        int a = contacts.size();
        int contactId = 0;
        while(type != 4){
            conID++;
        System.out.println("[1] Personal Contact");
        System.out.println("[2] Business Contact");
        System.out.println("[3] Display Contacts");
        System.out.println("[4] to quit");
        type = input1.nextInt();
        if(type == 4){
            System.out.println("Goodbye");
            break;
            }
        else if (type == 3){
            displayContacts(contacts);
            System.out.println("Please select the number of the contact you would like more information on.");
            Scanner selection = new Scanner(System.in);
            int con = selection.nextInt() - 1;
            Contacts info = contacts.get(con);
            System.out.println(info);
            break;
            }
            
        Scanner inputs = new Scanner(System.in);
        //System.out.println("Please enter a unique numeric ContactId: ");
        contactId = conID;
        System.out.println("Please enter First Name: ");
        String firstName = inputs.nextLine();
        if (firstName == null) {
            break;
        }
        System.out.println("Please enter Last Name: ");
        String lastName = inputs.nextLine();
        if (lastName == null) {
            break;
        }
        System.out.println("Please enter Address: ");
        String address = inputs.nextLine();
        System.out.println("Please enter Phone Number: ");
        String phoneNumber = inputs.nextLine();
        System.out.println("Please enter Email Address: ");
        String emailAddress = inputs.nextLine();
        if(type == 1){
           System.out.println("Please enter Birthday: ");
           String dateofBirth = inputs.nextLine();
           Contacts personal = new PersonalContact(contactId, firstName, lastName, address, phoneNumber, emailAddress, dateofBirth);
           contacts.add(personal);
        }
        else if(type == 2){
            System.out.println("Please enter Job Title: ");
            String jobTitle = inputs.nextLine();
            System.out.println("Please enter Organization: ");
            String organization = inputs.nextLine();
            Contacts business = new BusinessContact(contactId, firstName, lastName, address, phoneNumber, emailAddress, jobTitle, organization);
            contacts.add(business);
        }
        }
        }
        public static void displayContacts(ArrayList<Contacts> contacts){
        for (Contacts c: contacts){
            c.displayContacts();
        }
        }
        public static void displayOne(ArrayList<Contacts> contacts) {
            for (int j = 0; j < contacts.size(); j++) {
                {
                 contacts.get(j);
                }
            }
            }
        }
