Hi Kc,
I don't know which one of the homeworks you are talking. The code seems
correct to me. Just one observation, you can define in the Person class
a member "AdressInterface address;" and have in the constructor:
// Constructor with arguments
Person(int cashSaving,
int retirementFund,
String firstName,
String lastName,
*AddressInterface* address) {
this.cashSaving = cashSaving;
this.retirementFund = retirementFund;
this.firstName = firstName;
this.lastName = lastName;
this.address = address;
}
In this way, the Person class is not dependent on the implementation
AddressImpl, but it is still possible to call the constructor like this:
Person person = new Person( 100, 200, "First", "Last", *new
AddressImpl( ...)*);
For e.g., let's assume that the Person class is written by your team,
but the AddressImpl by another team. You have to do your job, but the
other team didn't finish theirs, so you cannot create your Person class
without having error signs from NetBeans. One way to do it is to agree
on the interface with the other team. Write together the interface. Then
you can work to your Person class just referencing the interface,
without any error, and the other team can create AddressImpl just
implementing the AddressInterface. (Of course, AddressImpl must be ready
before someone can test the whole).
Hope it helps

Hi,
I am not sure this is the right way to do the workwork, please advise.
1. To implement MyOwnInterfac, I will need to create a reference
variable <address> of AddressImpl type in Person class, so i can use
it in the constructor and implement the getAddress method
// Constructor with arguments
Person(int cashSaving,
int retirementFund,
String firstName,
String lastName,
AddressImpl address) {
this.cashSaving = cashSaving;
this.retirementFund = retirementFund;
this.firstName = firstName;
this.lastName = lastName;
this.address = address;
}
public AddressInterface getAddress() {
return address;
}
2. I will also need to create a reference variable <address> of
AddressImpl type in order to create object instance of Person class
AddressImpl address = new AddressImpl("Malaysia", "Jalan
Ismail", 30);
Person person1 = new Person(10000, 20000, "Sang", "Shin",
address);
Regards
KC
