    Question Inheritance problems

    Hey, this is my code so far, but how do I set the name in Contact using the variables in Name?

    public class Name extends Contact
    {
    private String fName;
    private String sName;

    public Name()
    {

    }

    public void setFName(String fName)
    {
    this.fName = fName;
    }

    public void setLName(String sName)
    {
    this.sName = sName;
    }
    }



    public class Contact
    {
    private Name fName;
    //private String sName;
    //private String street;
    //private String town;
    // private String postcode;

    public Contact()
    {

    }

    private void contacts(String fName, String sName, String street, String town, String postcode)
    {
    Name.fName = fName;


    }
    }

    Thanks in advance, Tom

    Default Re: Inheritance problems

    Your problem is your confusion between the variables and the inheritance/classes. The statement private Name fName; in class Contact is a backward reference. if fName is the same for both classes you won't need to declare it in your class Name but define fName as protected (only for inheritance) or public (also from outside) in the "mother" class Contact. Your code won't make any sense and is logically wrong. It's also not a recursive technique.
    public class Contact{
             prrotected String fName; // or public String fName;
             //wrong: private Name fName; 
    ..
