for (int i = 0; i < bArray.length; i++) {
    String sTemp = Integer.toHexString(0xFF & bArray[i]);
    if (sTemp.length() < 2) {
        sb.append(0);

return sb.toString();
StringmakeHex(int val)
make Hex 
String ret = "";
String[] hexChars = new String[16];
for (int i = 0; i < 10; i++) {
    hexChars[i] = String.valueOf(i);
hexChars[10] = "A";

voidappendHexJavaScriptRepresentation(int codePoint, Appendable out)
Returns a javascript representation of the character in a hex escaped format. 
if (Character.isSupplementaryCodePoint(codePoint)) {
    char[] surrogates = Character.toChars(codePoint);
    appendHexJavaScriptRepresentation(surrogates[0], out);
    appendHexJavaScriptRepresentation(surrogates[1], out);
    return;
out.append("\\u").append(HEX_CHARS[(codePoint >>> 12) & 0xf])
        .append(HEX_CHARS[(codePoint >>> 8) & 0xf])
...
voidappendHexJavaScriptRepresentation(StringBuilder sb, char c)
Although this is a rather specific method, it is made public because it is also used by the JSCompiler. 
try {
    appendHexJavaScriptRepresentation(c, sb);
} catch (IOException ex) {
    throw new RuntimeException(ex);
byte[]hexToBytes(CharSequence str)
Convert a string of hex digits to a byte array, with the first byte in the array being the MSB. 
byte[] bytes = new byte[(str.length() + 1) / 2];
if (str.length() == 0) {
    return bytes;
bytes[0] = 0;
int nibbleIdx = (str.length() % 2);
for (int i = 0; i < str.length(); i++) {
    char c = str.charAt(i);
...
inthexValue(char c)
hex Value 
if ((c >= '0') && (c <= '9')) {
    return (c - '0');
} else if ((c >= 'a') && (c <= 'f')) {
    return (c - 'a') + 10;
} else {
    return (c - 'A') + 10;
booleanisHex(char c)
is Hex 
return ((c >= '0') && (c <= '9')) || ((c >= 'a') && (c <= 'f'))
        || ((c >= 'A') && (c <= 'F'));
StringgetHexString(int[] b)
get Hex String 
return getHexString(b, HEX_STRING_BLANK_SPLIT);
StringgetHexString(int[] b, String splitString)
get Hex String 
StringBuffer sb = new StringBuffer();
for (int c : b) {
    String strData = Integer.toHexString(c);
    if (strData.length() == 1) {
        sb.append("0").append(strData);
    } else {
        sb.append(strData);
    sb.append(splitString);
return sb.toString().trim();
