Method

byte[]addLeadingZero(byte[] value)
add Leading Zero 
byte[] result = new byte[value.length + 1];
result[0] = 0;
System.arraycopy(value, 0, result, 1, value.length);
return result;
StringaddLeadingZero(final int value)
add Leading Zero 
if (value < 10) {
    return "0" + value; 
} else {
    return String.valueOf(value);
StringaddLeadingZero(String aString, int aAmountOfZeros)
add Leading Zero 
final int stringLength = aString.length();
if (stringLength < aAmountOfZeros) {
    for (int i = 0, l = aAmountOfZeros - stringLength; i < l; ++i) {
        aString = "0" + aString;
return aString;
StringaddLeadingZeroesTo16BitBinaryString(String binaryValue)
add Leading Zeroes To Bit Binary String 
int length = binaryValue.length();
while (binaryValue.length() < 16) {
    binaryValue = "0" + binaryValue;
return binaryValue;
StringaddLeadingZeros(Object number, int places)
add Leading Zeros 
if (number == null)
    return null;
if (number instanceof String)
    try {
        Double.valueOf((String) number);
    } catch (Throwable t) {
        throw new IllegalArgumentException(
                "addLeadingZeros, problem with string value " + number + ": " + t.getCause());
...
StringaddLeadingZeros(String deweyCallNum)
adds leading zeros to a dewey call number, when they're missing. 
String result = deweyCallNum;
String b4Cutter = getPortionBeforeCutter(deweyCallNum);
String b4dec = null;
int decIx = b4Cutter.indexOf(".");
if (decIx >= 0)
    b4dec = deweyCallNum.substring(0, decIx).trim();
else
    b4dec = b4Cutter.trim();
...
StringaddLeadingZeros(String number, int maxDigits)
adds some leading '0' to the sting until the length maxDigits is reached 
StringBuilder result = new StringBuilder(number);
while (result.length() < maxDigits) {
    result.insert(0, "0");
return result.toString();
StringaddLeadingZeros(String s, int nZeros)
Prepends nZeros zeros to the given string and returns the resulting string. 
char[] zeros = new char[nZeros];
for (int i = 0; i < zeros.length; i++)
    zeros[i] = '0';
return String.valueOf(zeros) + s;
StringaddLeadingZeros(String str)
add Leading Zeros 
String nStr = str;
while (nStr.length() < 15) {
    nStr = "0" + nStr;
return nStr;
StringaddLeadingZerosToNumber(long number, int length)
add Leading Zeros To Number 
if (length <= ((int) Math.log10(number) + 1))
    return String.valueOf(number);
return String.format("%0" + length + "d", number);
