Java Array in a constructor is not working

A strange thing happened to me which I am not able to explain to myself, so I hope someone can explain it to me. The situation is the following: I have an class called "Item". Instances of these class are instantiated with a name and two integer arrays, representing some values for this item (the meaning of these values are not important for this).

This works:

private Item item = new Item("Something", null, null);

This isn't:

private Item item = new Item("Something", {"A", "B"}, null);

This however works:

private String[] str = {"A", "B"};
private Item item = new Item("Something", str, null);

So.. my question is: Why? I absolutelty don't see why the second method isn't possible.

The compiler doesnt automatically know the type of the array so it has to be expressly defined when declaring it as an expression

private Item item = new Item("Something", new String[] {"A", "B"}, null);
