String object is computed as
usings[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]
int arithmetic, where s[i] is the
ith character of the string, n is the length of
the string, and ^ indicates exponentiation.
(The hash value of the empty string is zero.)public static int byteArrayHashCode(byte[] bytes)
