No you dont. Arrays are all bounds checked; ..., that is, the following code will throw an exception: ================================ class Foo { static { int[] m = new int[2]; System.out.println(m[34]); } } ================================ What do you mean by "overflow"? Do you mean this? ================================ class Foo { static { int m = Integer.MAX_VALUE; int k = Integer.MAX_VALUE + Integer.MAX_VALUE; System.out.println(m); System.out.println(k); System.exit(0); } } ================================ if so, I don't see how that is an issue. -- Michael On 3/29/06, Andrew van der Stock <vanderaj () greebo net> wrote:
