Using Variable Length Argument in Constructor

Question

Hi All,
I am tring to create class Address which represent Address of different people, However not all the information will be available for all the entries.I am thinking of using a Variable Length Argument in Constructor (String).Now I am unable to create a proper constructor as If few of the information say city is missing then how should the cons behave.Any help is highly appreciated.
Below is the class
package javaProg.completeReferance;
import java.util.*;
import javaProg.completeReferance.*;
public class Address
     private String name,address,city,pincode;
     public Address(String ...)
}

The problem with using a variable argument constructor here is that you don't know which of the pieces of information are being supplied. Var args is nice if the information being passed has a known "meaning", but may consist of an unknown number of parts (although it's little better than an array): but that's not what you have here.
If some of the arguments have sensible default values (even null) you could have something likepublic Address(String name, String address, String city, String pincode) {
    this.name = name;
    this.address = address;
    this.city = city;
    this.pincode = pincode;
public Address(String name, String address) {
    this(name, address, null, null, -1);
}(I'm treating pincode as an int by way of example.)
