Method

Stringbin2hex(byte[] arr)
Converts a byte array to hex string 
StringBuffer sb = new StringBuffer();
for (int i = 0; i < arr.length; i++) {
    String str = Integer.toHexString((int) arr[i]);
    if (str.length() == 2)
        sb.append(str);
    if (str.length() < 2) {
        sb.append("0");
        sb.append(str);
...
Stringbin2Hex(byte[] b)
bin Hex 
return bin2Hex(b, 0, b.length);
byte[]bin2Hex(byte[] bin)
Binary byte[] to Heximal byte[] 
byte[] hex = new byte[2 * bin.length];
for (int i = 0, j = 0; i < bin.length; i++, j += 2) {
    int iByte = bin[i];
    if (iByte < 0)
        iByte += 256;
    int i4Bit = iByte >> 4;
    if (i4Bit < 10)
        hex[j] = (byte) ('0' + i4Bit);
...
Stringbin2hex(final byte[] b)
Simple binary-to-hexadecimal conversion. 
if (b == null) {
    return "";
StringBuffer sb = new StringBuffer(2 * b.length);
for (int i = 0; i < b.length; i++) {
    int v = (256 + b[i]) % 256;
    sb.append(hex.charAt((v / 16) & 15));
    sb.append(hex.charAt((v % 16) & 15));
...
Stringbin2hex(final byte[] base)
binhex 
if (base != null) {
    char[] c = new char[base.length * 2];
    int i = 0;
    for (byte b : base) {
        int j = b;
        j = j & 0xff; 
        c[i++] = TOHEX[j / 0x10];
        c[i++] = TOHEX[j % 0x10];
...
intbin2hex(int digit)
binhex 
final int isLessOrEqual9 = (digit - 10) >> 31;
final int bin2hexAsciiDistance = 48 + ((~isLessOrEqual9) & 39);
return digit + bin2hexAsciiDistance;
Stringbin2Hex(String bin)
bin Hex 
int intVal = parseBin(bin);
return normalizeNumber(Integer.toHexString(intVal), bin.length() / 4);
Stringbin2hex(String bin)
binhex 
char[] digital = "0123456789ABCDEF".toCharArray();
StringBuffer sb = new StringBuffer("");
byte[] bs = bin.getBytes();
int bit;
for (int i = 0; i < bs.length; i++) {
    bit = (bs[i] & 0x0f0) >> 4;
    sb.append(digital[bit]);
    bit = bs[i] & 0x0f;
...
Stringbin2hex(String str)
binhex 
String s = dec2hex(Integer.parseInt(str, 2));
return s;
StringbinaryString2hexString(String bString)
binary Stringhex String 
if (bString == null || bString.equals("") || bString.length() % 8 != 0)
    return null;
StringBuffer tmp = new StringBuffer();
int iTmp = 0;
for (int i = 0; i < bString.length(); i += 4) {
    iTmp = 0;
    for (int j = 0; j < 4; j++) {
        iTmp += Integer.parseInt(bString.substring(i + j, i + j + 1)) << (4 - j - 1);
