Class interaction

Question

I'm a bit stuck:
How would I go about transferring Strings from an ActionListener class to another class and using those Strings as instance variables to create an object in the class I am transferring to.
It's a bit complicated to understand, but here is my code for part of the ActionListener class:
    public void actionPerformed(ActionEvent event) {      
        if (event.getSource() == "addButton") { 
            getName = gui.getNameInfo();                          
            getDisplay = gui.getDisplayInfo();
            getWork = gui.getWorkInfo();
            getHome = gui.getHomeInfo();
            getMobile = gui.getMobileInfo();
        }I've also got another class (a subclass of an abstract class) where I want these String variables to go and use themselves to create an object.

I think I know what you mean, but not entirely sure, so how about this:
In the constructor to your gui class where you capture the strings, pass in an ArrayList.
Then every time you create a new address object, add that object to the ArrayList.
Something like ArrayList.add(address);
Just note though - you must create the ArrayList outside your gui class, so that when you pass it in the constructor, it is already created. If you try to create a new one inside your constructor, you won't be able to see it from the class that calls your constructor.
so:
public class myGuiClass{
ArrayList arrayOfAddresses;
myGuiClass(ArrayList arrayOfAddresses){
this.arrayOfAddresses = arrayOfAddresses;
You can then use the ArrayList inside your GUI class, and when you exit the class and the class is destroyed, the ArrayList will still exist in the calling class.
And how to treat the names of the objects? If you wanted you could give each object a unique field - a name might be duplicated in a large address book, so consider giving them unique ids.
