Unlike T is not a primitive, its quite easy:

List list = Arrays.asList(new String[] {”s1″, “s2″});

Using toArray is a bit odd the first time you see it when you haven’t read much about how generics are implemented in Java. The real PITA is trying to go the other way, from T[] to Iterable. Especially if you are trying to include support for arrays of primitives.

Yes, this is irritating. Usually, I don’t use the “create in place” feature and end up writing code like

public static final EMPTY_STRING_ARRAY String[] = new String[0];

// Later

List strings = …

String[] stringArray = strings.toArray(EMPTY_STRING_ARRAY);

I can use EMPTY_STRING_ARRAY more than once, but the code still is ugly.
