To the first question, No. Do not assume AddressImpl address; gets
used in Person class.
Person should use private AddressInterface address; in the variables
list and
// Implement MyOwnInterface method
public AddressInterface getAddress() {
return address;
}
This needs to be public here because you will use it in Main.class.
And there you will store address data using the AddressImpl.class.
An instance of AddressInterface.class holds the address data. I know
it seems confusing that an interface with no variables is able to
store anything but that is the magic of using interface instances. It
is still a class and we gave whatever holds the address data that
classification.
from Main.class
AddressInterface address1 = person1.getAddress();// data = get method
