The list of methods to do Hex Calculate are organized into topic(s).

Method

StringtoHexString(byte[] b)
Convenience method to print byte array as hexadecimal string. 
StringBuffer sb = new StringBuffer();
for (int i = 0; i < b.length; i++)
    int c = ((b[i]) >>> 4) & 0xf;
    sb.append(hex[c]);
    c = ((int) b[i] & 0xf);
    sb.append(hex[c]);
return sb.toString();
StringtoHexString(byte[] b)
Convert bytes to hex string (all lower-case). 
StringBuilder sb = new StringBuilder(b.length << 2);
for (byte x : b) {
    int hi = (x & 0xf0) >> 4;
    int lo = x & 0x0f;
    sb.append(HEX_CHARS[hi]);
    sb.append(HEX_CHARS[lo]);
return sb.toString().trim();
...
StringtoHexString(byte[] b, int off, int len)
to Hex String 
StringBuffer buf = new StringBuffer();
int end = off + len;
for (; off < end; off++) {
    buf.append(hexChars[(b[off] & 0xf0) >>> 4]);
    buf.append(hexChars[b[off] & 0x0f]);
return buf.toString();
StringtoHexString(byte[] b, int off, int len)
Convert a byte array to a big-endian ordered hexadecimal string. 
char[] buf = new char[len * 2];
for (int i = 0, j = 0, k; i < len;) {
    k = b[off + i++];
    buf[j++] = HEX_DIGITS[(k >>> 4) & 0x0F];
    buf[j++] = HEX_DIGITS[k & 0x0F];
return new String(buf);
StringtoHexString(byte[] ba)
to Hex String 
StringBuilder str = new StringBuilder();
for (int i = 0; i < ba.length; i++) {
    str.append(String.format("%x", new Object[] { Byte.valueOf(ba[i]) }));
return str.toString();
StringtoHexString(byte[] ba)
Konvertiert ein Byte-Array in einen Hex-String mit zwei Hex-Zeichen je Byte. 
StringBuffer sb = new StringBuffer(ba.length * 2);
for (byte element : ba) {
    sb.append(toHexString(element));
return sb.toString();
StringtoHexString(byte[] ba, int offset, int length)
converts String to Hex String. 
char[] buf;
buf = new char[length * 2];
for (int i = offset, j = 0, k; i < offset + length;) {
    k = ba[i++];
    buf[j++] = HEX_DIGITS[(k >>> 4) & 0x0F];
    buf[j++] = HEX_DIGITS[k & 0x0F];
return new String(buf);
...
StringtoHexString(byte[] binary)
To hex string. 
if (binary != null) {
    StringBuffer str = new StringBuffer(binary.length * 2);
    for (int i = 0; i < binary.length; i++) {
        int v = (binary[i] << 24) >>> 24;
        str.append((v < 0x10 ? "0" : "") + Integer.toHexString(v));
    return str.toString();
return null;
StringtoHexString(byte[] binaryData)
Creates a human-readable hex-String out of a byte-array (e.g. 
if (binaryData != null) {
    char[] text = new char[binaryData.length << 1];
    int j = 0;
    byte b;
    for (int i = 0; i < binaryData.length; ++i) {
        b = binaryData[i];
        text[j++] = hexDigits[(b & 0xf0) >> 4];
        text[j++] = hexDigits[b & 0x0f];
...
StringtoHexString(byte[] block)
Converts a byte array to hex string 
StringBuffer buf = new StringBuffer();
int len = block.length;
for (int i = 0; i < len; i++) {
    byte2hex(block[i], buf);
    if (i < len - 1) {
        buf.append(":");
return buf.toString();
