How a static map can be initialized

Question

How would you initialize a static Map in Java?

Answer 1

public class initialize

 {
    private static final Map<Integer, String> Map;
    static 

    {
        Map<Integer, String> aMap = ....;
        aMap.put(1, "one");
        aMap.put(2, "two");
        Map = Collections.unmodifiableMap(aMap);
    }
}

Answer 2

public class Test {
    private static final Map<Integer, String> MY_MAP = createMap();

    private static Map<Integer, String> createMap() {
        Map<Integer, String> result = new HashMap<Integer, String>();
        result.put(1, "one");
        result.put(2, "two");
        return Collections.unmodifiableMap(result);
    }
}
