Description

The list of methods to do Byte Array Compare are organized into topic(s).

Method

intmemcmp(byte[] bytes, byte[] bytes2, int nbElem)
Memory comparison 
for (int i = 0; i < nbElem; i++) {
    Byte left = bytes[i];
    Byte right = bytes2[i];
    int compare = left.compareTo(right);
    if (compare != 0) {
        return compare;
return 0;
intmemcmp(byte[] s1, int s1Size, int s1offset, byte[] s2, int s2Size, int s2offset)
Equiv of C library memcmp(). 
int n = s1Size - s1offset;
if (n > (s2Size - s2offset)) {
    n = s2Size - s2offset;
for (int i = 0; i < n; i++) {
    if (s1[i + s1offset] != s2[i + s2offset]) {
        return s1[i + s1offset] < s2[i + s2offset] ? -1 : 1;
return 0;
intmemcmp(final byte[] a, final byte[] b, int length)
memcmp 
for (int i = 0; i < length; i++) {
    if (a[i] != b[i]) {
        return (a[i] & 0xFF) - (b[i] & 0xFF);
return 0;
intmemcmp(final byte[] first, final int firstStart, final byte[] second, final int secondStart, int size)
memcmp 
assert firstStart + size <= first.length;
assert secondStart + size <= second.length;
int cmp;
for (int i = 0; i < size; i++) {
    if ((cmp = (first[firstStart + i] & 0xff) - (second[secondStart + i] & 0xff)) != 0) {
        return cmp;
return 0;
intmemcmp(List header, String string, int size)
memcmp 
for (int i = 0; i < size; i++) {
    if (header.get(i) != (byte) string.charAt(i))
        return 1;
return 0;
