Definition of Arrays.hashCode(byte[]) Arrays.hashCode(byte[]) is a very simple method that computes the hash code for a given byte[] array with elements b [0], b [1], …, b [ n −1] using the recursion The method was implemented up to OpenJDK 20 as static int hashCode(byte[] b) { if (b == null) return 0; int h = 1; for (byte q : b) { h = 31 * h + q; } return h; } The iterative processing of individual bytes does not allow for many compiler optimizations.
