// You can use the de.enough.polish.util.ArrayList just as the usual J2SE ArrayList:

package com.apress.adress;
import de.enough.polish.util.ArrayList;

public class AdressBook {
	ArrayList contactsList;

	public AdressBook() {
		super();	
	}

	public void addContact( Contact contact ) {
		this.contactsList.add( contact );
	}

	public Contact[] searchContacts( String pattern ) {
	ArrayList matchingContacts = new ArrayList();
	for ( int i = this.contactsList.size(); --i >= 0; ) {
		Contact contact = (Contact) this.contactsList.get( i );
		if ( contact.pattern.indexOf(pattern) != -1 ) {
			matchingContacts.add( contact );
		}
	}
		return (Contact[]) matchingContacts.toArray(
			new Contact[ matchingContacts.size() ]);
	}
}

package com.apress.adress;
public class Contact {
	public String firstName;
	public String lastName;
	public String chatAddress;
	public String emailAddress;
	public String pattern;

	public Contact(String firstName, String lastName,
		String chatAddress, String emailAddress)
	{
		this.firstName = firstName;
		this.lastName = lastName;
		this.chatAddress = chatAddress;
		this.emailAddress = emailAddress;
		this.pattern = firstName + lastName + chatAddress + emailAddress;
	}
}
