Converts a String or an array of character bytes representing hexadecimal values into an array of bytes of those same values.

Usage

From source file:Main.java

public static List<byte[]> hexToListBytesArray(String s) throws DecoderException {
    List<String> listHex = new ArrayList<String>();
    if (s.length() == 2) {
        listHex.add(s);//from   ww  w  .  j  ava 2 s . c o m
    } else if (s.length() > 2 && ((s.length() % 2) == 0)) {
        for (int i = 0; i < s.length(); i++) {
            String ss = s.substring(i, i + 2);
            i = i + 1;
            listHex.add(ss);
        }
    } else {
        return null;
    }
    Hex hex = new Hex();

    List<byte[]> listByteArray = new ArrayList<byte[]>();
    for (String sh : listHex) {
        listByteArray.add(hex.decode(sh.getBytes()));
    }
    return listByteArray;
