How do you use long in a HashMap?

I am trying to use long instead of integer to create a phoneBook. It keeps saying its an integer and its to large.

import java.util.HashSet;
import java.util.HashMap;
/**
 * Write a description of class MapTester here.
 *
 * @author (your name)
 * @version (a version number or a date)
 */
public class PhoneBook
{
private HashMap<String, Long> phoneBook = new HashMap<String, Long> ();
private HashSet<String, Long> phoneBook = new HashSet<String, Long>();

public PhoneBook()
{
phoneBook.put("Homer Jay Simpson", 53193924587);
phoneBook.put("Peter Griffin", 53154321945);
phoneBook.put("Apu Nahasapeemapetilon", 53142344418);
}


/**
 * Method that takes two parameters the name and telephone number and then attempts to add information into the phonebook
 */
public void phoneBook(String name, long number)

{
if(phoneBook.put(name, number);
}


public String lookupNumber(String name)

{
return phoneBook.get(name);
}
}
