adding custom objects to a list field inside a custom object

Question

I am trying to add custom objects to a list, which is a field inside another custom object.

let me explain reasoning. I have an arraylist of clients(company's) these clients have contacts(contact persons who work at the client). for this reason I am trying to add these contacts to a arraylistfield inside the client object. but I don't know how to add these to the arraylist of the selected client or how to call on a method inside the clientsobjectclass with initialization, since the constructor asks all the client fields.

Client Object:

package Activities.Main.Objects;

import android.util.Log;
import Main.Arrays.ClientsArray;

import java.util.ArrayList;
import java.util.List;

public class Clients {
    private String Name;
    private String Phone;
    private String Email;
    private String URL;
    private Double Turnover;
    private String VisitAddress;
    private String VisitCity;
    private String VisitZipcode;
    private String VisitCountry;
    private String PostalAddress;
    private String PostalCity;
    private String PostalZipcode;
    private String PostalCountry;
    private List<Contacts> Contactlist =  new ArrayList<Contacts>();


    public Clients(String Name, String Phone, String Email, String URL, Double Turnover,
                   String VisitAddress, String VisitCity, String VisitZipcode, String VisitCountry,
                   String PostalAddress, String PostalCity, String PostalZipcode, String PostalCountry){
            super();
            this.Name = Name;
            this.Phone = Phone;
            this.Email = Email;
            this.URL = URL;
            this.Turnover = Turnover;
            this.VisitAddress = VisitAddress;
            this.VisitCity = VisitCity;
            this.VisitZipcode = VisitZipcode;
            this.VisitCountry = VisitCountry;
            this.PostalAddress = PostalAddress;
            this.PostalCity = PostalCity;
            this.PostalZipcode = PostalZipcode;
            this.PostalCountry = PostalCountry;
    }


    public void add(){
        Contactlist.add(new Contacts("Oscar", "Hugo", "Bokhorst", "Developer", "0616397853", "0513631325", "[email protected]"));
        int sizeCheck = Contactlist.size();
        Log.d("Hello", "=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f=f = contactlist size = " + sizeCheck);

    }


    public String getName() {
        return Name;
    }

    public String getPhone() {
        return Phone;
    }

    public String getEmail() {
        return Email;
    }

    public String getURL() {
        return URL;
    }

    public Double getTurnover() {

        return Turnover;
    }

        return VisitAddress;
    }

    public String getVisitCity() {
        return VisitCity;

    public String getPostalZipcode() {
        return PostalZipcode;
    }

    public String getPostalCountry() {
        return PostalCountry;
    }

    public List<Contacts> getContactlist(){
        return Contactlist;
    }
}

Use the constructor to assign the ArrayList<Contacts> also. In you Fragment or Activity create a new list -

List<Contacts> Contactlist =  new ArrayList<Contacts>();

Then add all the Contacts to this list for this particular client.

Then simply pass it to the constructor when you're creating a Client class object with the rest of the details -

Client c = new Client(name, phone, ......... , Contactlist);

In your Client class modify the constructor to accept the list also -

public Clients(String name, String phone, .......... , List Contactlist){
    this.Contactlist = Contactlist; //List assigned
}

If you want to add more contacts to this list then simply access the list though the getter method and add more contacts -

client.getContactList().add(contact);
