Class initialization error!

package language;

import java.util.ArrayList;
import java.util.Iterator;

public class Language {

public static final Language ROMANIAN = new Language(0);
	public static final Language RUSSIAN = new Language(1);
	public static final Language ENGLISH = new Language(2);
	public static final Language DEFAULT = ENGLISH;
	
	private static final ArrayList<Language> allLanguages = new ArrayList<Language>();
	private int language;

public static Language getLanguageWithId(int id) throws NoSuchLanguageException {
		Iterator it = allLanguages.iterator();
		Language result = null;
		while (it.hasNext()) {
			Language lang = (Language) it.next();
			if (lang.getLanguageId() == id) {
				result = lang;
				break;
			}
		}
		if (result == null) {
			throw new NoSuchLanguageException("There is no language with such id");
		}
		return result;
	}

public Language(int language) {
		this.language = language;
		//allLanguages.add(this);
	}

public int getLanguageId() {
		return language;
	}

public static void main(String[] args) {
		System.out.println("Hello");
	}
}

This goes ok! If i decomment this line
from constructor, i get such error:

What's the problem, i have no idea

Ooops! Problem solved!

I've just put this line:

before these ones:

Vadim, the problem is simple, your individual references are initialized before the ArrayList. That's why the ArrayList is null when you try to add the element to it. Try this sequence of declaration

[Edit: Oops, I'm late

Thanks anyway!
