List of adresses, contact details

Dear dr, we faced a problem in adding a new customer please give us any hint regarding how to add a list of addresses and a list of contact details how could we implement that in the UI also😣😣

Customer is class having:
customerId: Int, companyName: String, address: Address, contractDetails: ContactDetails
Address is a class having:
street: String, city: String, country: String
ContactDetails is a class having:
firstName: String, lastName: String, mobile: String, email: String

In your app you will have a customers : List<Customer>. Then you will add/update/delete items from the customers list. Plenty of lecture and lab examples that show you how to do so.
You do NOT need a list of addresses or a list of contact details, you simply need a list of customers.
