A Key- Value pair type is wht will be useful for you. Check http://www.java2s.com/Tutorial/Java/0140__Collections/AddingKeyValuePairs.htm or jsut search for "key value pair java" — ray, Sep 07 '14 at 08:21

Java Vector is not commonly used anymore. You could use a combination of lists and maps, as explained in this post, but maybe you could just make Person objects with name and address and add them to an ArrayList in stead?

import java.util.ArrayList;
import java.util.List;

public class Main {

    public static void main(String[] args){

        List<Person> persons = new ArrayList<>();
        persons.add( new Person("John", "Canada") );
        persons.add( new Person("John", "USA") );
        persons.add( new Person("John", "Mexico") );

        //java 8
        persons.stream().forEach((p) -> {
            System.out.println("Name: " + p.getName() +", Address: "+ p.getAddress());
        });

        //java 7
        for(Person p : persons){
            System.out.println("Name: " + p.getName() +", Address: "+ p.getAddress());
        }

    }

}

class Person {

    private final String name;
    private final String address;

    public Person(String name, String address){
        this.name = name; 
        this.address = address;
    }

    public String getName() {
        return name;
    }

    public String getAddress() {
        return address;
    }

}
