voidand(byte[] a, int offsetA, byte[] b, int offsetB, byte[] dst, int dstOffset, int length)
AND length number of bytes from a with b using the syntax ( a[i] & b[i] ) and store the result in dst 
for (int i = 0, aI = offsetA, bI = offsetB, dstI = dstOffset; i < length; i++, aI++, bI++, dstI++) {
    dst[dstI] = (byte) (a[aI] & b[bI]);

and 
if (data1.length != data2.length) {
    throw new IllegalArgumentException(
            "array lenth does NOT match, " + data1.length + " vs " + data2.length);
