Method

voidcopyBytesWithin(byte[] bytes, int target, int start, int end)
copy Bytes Within 
System.arraycopy(bytes, start, bytes, target, end - start);
voidmemcpy(byte[] dest, int doff, byte[] src, int soff, int len)
memcpy 
for (int i = 0; i < len; i++) {
    dest[doff + i] = src[soff + i];
voidmemcpy(byte[] destBytes, byte[] srcBytes, int numBytes)
memcpy 
for (int i = 0; i < numBytes; i++) {
    destBytes[i] = srcBytes[i];
intmemcpy(byte[] dst, int dst_offset, byte[] src, int src_offset, int length)
Copy contents of one array of bytes into another. 
if ((dst != null) && (src != null)) {
    if (dst.length < (dst_offset + length)) {
        croak("dst.length = " + dst.length + ", but " + "dst_offset = " + dst_offset + " and length = "
                + length + ".");
    if (src.length < (src_offset + length)) {
        croak("src.length = " + src.length + ", but " + "src_offset = " + src_offset + " and length = "
                + length + ".");
