java: primitive arrays -- are they initialized?

Question

If I use a statement in my code like

int[] a = new int[42];

Will it initialize the array to anything in particular? (e.g. 0) I seem to remember this is documented somewhere but I am not sure what to search for.

Answer 1

At 15.10 Array Creation Expressions the JLS says

[...] a single-dimensional array is created of the specified length, and each component of the array is initialized to its default value

and at 4.12.5 Initial Values of Variables it says:

For type int, the default value is zero, that is, 0.
