Items not being added through GUI but can be added to ArrayList from input file

I had to redesign the classes (it was dictated to me that they be as they are - Person,Friend,Address) the rest is my own AddressBook (main class), AddressBookGUI, BookActions, and Contact (should be ContactList) - for processing objects into an ArrayList.
 AddressBook.java  AddressBookGUI.java BookActions.java Contact.java Person.java Friend.java

these are what I am working with.

The problem I am now having is retrieving text from the textfields into the Friend Constructor in the addNewContact() method in the BookAction class.
 
public void addNewContact() {
        System.out.println(c.contactsSize());
        String lName = abg.lastName.getText();
        String fName = abg.firstName.getText();
        String mName = abg.middleName.getText();
        String hPhone = abg.homePhone.getText();
        String cPhone = abg.cellPhone.getText();
        String streetName = abg.streetName.getText();
        String cityName = abg.cityName.getText();
        String stateName = abg.stateName.getText();
        String zipCode = abg.zipCode.getText();

        f = new Friend(lName, fName, mName, hPhone, cPhone);
        a = new Address(streetName, cityName, stateName, zipCode);
        c.addContacts(f);
        clearAll();
        System.out.println(c.getContacts());
    }

Open in new window


I get a null pointer exception from trying to retrieve the ArrayList size or the same exception when trying to add the friend object.

I'm not sure what is wrong becaue the arrayList returns "11" as a size and also displays all the contact objects read from the input file.

Address.java

c is null, you need to initialise it before adding things to it
