byte[]byteToBitsArray(byte b)
This method convert a single byte to a 8-bytes array. 
byte[] result = new byte[8];
short val = (short) (b + 128);
for (int i = 0; i < 8; i++) {
    result[7 - i] = (byte) (val % 2);
    val /= 2;
return result;
StringbyteToBitStr(byte b)
byte To Bit Str 
String zero = "00000000";
String s = Integer.toBinaryString(b);
return zero.substring(0, 8 - s.length()) + s;
