Long in Java has size 2^63-1. But if I write a code like this, my IDE says Incompatible types: required int but found long.
long [] array = new long[4_000_000_000L];
What is the problem here?

1I would avoid doing this. Consider using a sparse array or a database instead. – Hovercraft Full Of Eels Jul 11 '15 at 15:49

TL;DR: the size of an array must not exceed the maximum integer value, which is `2^31 - 1 = 2_147_483_647` (In response to the duplicate entry). – Turing85 Jul 11 '15 at 15:53
