Method

StringtoHex(int color)
to Hex 
String rv = Integer.toHexString(color);
if (color <= 0x0F)
    return "0" + rv;
else
    return rv;
chartoHex(int decimalDigit)
to Hex 
return decimalDigit < 10 ? (char) (decimalDigit + '0') : (char) (decimalDigit - 10 + 'A');
StringtoHex(int h, int minDigit)
to Hex 
char[] digits = new char[8];
int d = 7;
do {
    digits[d--] = hexDigits[h & 0xf];
    h >>>= 4;
    --minDigit;
} while (h != 0 || minDigit > 0);
return new String(digits, d + 1, 7 - d);
...
chartoHex(int i)
Translates an int into a hex char. 
if (i >= 0 && i <= 9)
    return (char) ('0' + i);
if (i >= 10 && i <= 15)
    return (char) ('a' + i - 10);
throw new IllegalArgumentException("bad hex digit selector " + i);
StringtoHex(int i)
to Hex 
return "0x" + Integer.toHexString(i);
StringtoHex(int i)
Convert an integer to a hex string. 
String str = Integer.toHexString(0xFF & i);
if (str.length() < 2) {
    str = "0" + str;
return str;
StringtoHex(int i, String $default)
to Hex 
return i != -1 ? Integer.toHexString(i) : $default;
chartoHex(int myByte)
to Hex 
return HEX_DIGITS.charAt(myByte & 0xF);
chartoHex(int n)
to Hex 
if ((0 <= n) && (n <= 9)) {
    return (char) ('0' + n);
} else if ((10 <= n) && (n <= 15)) {
    return (char) (A + n);
} else {
    throw new IllegalArgumentException("" + n);
StringtoHex(int n)
to Hex 
StringBuilder sb = new StringBuilder();
if (n / 16 == 0) {
    return toHexUtil(n);
} else {
    String t = toHex(n / 16);
    int nn = n % 16;
    sb.append(t).append(toHexUtil(nn));
return sb.toString();
