    No on this line
    Address address = new Address(street, city, county, country);

    Inside the addEntry method it says "cannot find symbol - constructor address(java.lang.String, java.lang.String, java.lang.String ...)

    Look at the definition for the Address class. Does it have a constructor that matches the one you are using here:
    Address address = new Address(street, city, county, country);

    You need to
    either change the above line to match an existing constructor in the Address class
    or add a new constructor to the Address class that matches the above.

    Ahh i see it's becasue the constructor i had in my address class was:

    public Address(String street, String city, String county, String country, Postcode post)
        {
            this.street = street;
            this.city = city;
            this.county = county;
            this.country = country;
            this.post = post;
        }

    So i created another constructor
     public Address(String street, String city, String county, String country)
        {
            this.street = street;
            this.city = city;
            this.county = county;
            this.country = country;
        }

    Ok that will solve part of the problem.
    Now how will you put the Postcode object into the Address object?

    Yes the Address object is created by using the Address class definition.

    No, the Address class holds data for the address. Part of that data is the Postcode.
    Where do you first get the data for creating the Postcode object?
    That is where you should create the Postcode object and then pass that Postcode object to the Address class via the Address class's constructor.

    The data for the postcode object is within the postcode class.
    The postcode object is already being created in the class isn't it. And i thought i had passed it to the address class using

    private Postcode post;
    public Address(String street, String city, String county, String country, Postcode post)
        {
            this.street = street;
            this.city = city;
            this.county = county;
            this.country = country;
            this.post = post;
        }

    What you show in post#109 is where the Address class RECEIVES that data.
    Where do you SEND the data to the Address class by calling its constructor with the new statement?

    If the data is making it from the user to the Address class, then are you done with it?

    You must be more specific. What is "the data" that you use twice?

    As you said the data is created from the user and saved in the address class. The same thing happens in the name class to store the data for the name. The contact class needs to store both sets of data too as well doesn't it?

    I thought you were done with the Contact class and only had one small bit to do to finish the Address class.
    Why not finish one thing at a time. Finish the Address class.

    You need to get straight what goes into each class.
    Take a piece of paper and make a list for each of the classes of what data items go into that class.

    I'd tried doing that this morning creating a class diagram with the what i need for each class but got stuck when it came to the contact, address and textui classes

    For contact i just had this:

    Contact

    -name: Name
    -address: Address

    +Contact(Name name, Address address)

    Address - I understand holds a collection of contacts so i require an array

    Address

    -list: Contact[]
    -contact: Contact

    +AddressBook()

    From post#1
    2. address class - holds address details as string together with postcode.

    There is no collection of contacts.

    Sorry, I thought we were trying to finish up the Address class.
    Finish that first before doing another class.

    Okay the next is the Contact class - which needs to hold a name and an address

            this.name = name;
            this.address = address;
        }     
     
        @Override  
        public boolean equals(Object obj) {  
            if (this == obj)  
                return true;
