Question

How can I generate hash value for a byte array, in J2ME?

It doesn’t have to be very very secure but it should be fast.

Answer 1

As suggested by Josh Bloch in his Effective Java book:

public int hashCode() {    int result = 17;    for (int i = 0; i < array.length; i++) {       result = 31*result + (int)array[i];    }    return result; }
