Description

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

Method

StringtoHexString(final int i)
to Hex String 
return "0x" + Integer.toHexString(i);
StringtoHexString(final int value)
Returns a string representation of the integer argument as an unsigned integer in base 16. 
return "0x" + Integer.toHexString(value).toUpperCase();
StringtoHexString(final long num, final char paddingChar, int min, int max)

Internal use.

StringBuffer sb = new StringBuffer(Long.toHexString(num));
if (max < min) {
    return sb.toString();
while (sb.length() < max) {
    sb.insert(0, paddingChar);
return sb.substring(0, min);
...
StringtoHexString(int b)
to Hex String 
return "" + toHexChar(b >> 4) + toHexChar(b);
StringtoHexString(int b)
Returns a hex string representation of a 8 bit integer. 
char[] digits = new char[2];
b = b & 255;
digits[0] = hexDigits[b / 0x10];
digits[1] = hexDigits[b % 0x10];
return new String(digits);
StringtoHexString(int bits, int value)
to Hex String 
if (bits < 32)
    value &= (1 << bits) - 1;
String ret = Integer.toHexString(value);
int len = (bits + 3) / 4;
while (ret.length() < len)
    ret = "0" + ret;
if (ret.length() > len)
    ret = ret.substring(ret.length() - len);
...
StringtoHexString(int decimal, int stringLength)
Converts a decimal value to a hexadecimal string represention of the specified length. 
return String.format("%0" + stringLength + "X", decimal);
StringtoHexString(int decimal, int stringLength)
Converts a decimal value to a hexadecimal string represention of the specified length. 
StringBuilder sb = new StringBuilder(stringLength);
String hexVal = Integer.toHexString(decimal).toUpperCase();
int nofZeros = stringLength - hexVal.length();
for (int i = 0; i < nofZeros; i++) {
    sb.append('0');
sb.append(hexVal);
return sb.toString();
...
StringtoHexString(int i)
to Hex String 
final String zeroes = "0000000";
final String s = Integer.toHexString(i).toUpperCase();
if (s.length() < 8)
    return zeroes.substring(s.length() - 1) + s;
else
    return s;
StringtoHexString(int i)
convert an integer to a 2-digit hex string. 
String s = Integer.toHexString(i);
while (s.length() < 2) {
    s = "0" + s;
return s;
