Method

StringformatInteger(Integer value)
Formats an integer attribute. 
if (value != null) {
    return value.toString();
return null;
StringformatIntegerBase2WithLeadingZeros(long x, int length)
format Integer Base With Leading Zeros 
return pad(Long.toBinaryString(x), length, 1);
StringformatIntegerWithLeadingZeros(long x, int radix, int length)
format Integer With Leading Zeros 
return radix == 2 ? formatIntegerBase2WithLeadingZeros(x, length)
        : radix == 8 ? formatIntegerBase8WithLeadingZeros(x, length)
                : radix == 16 ? formatIntegerBase16WithLeadingZeros(x, length)
                        : formatIntegerBaseSomeWithLeadingZeros(x, radix, length);
StringformatIntents(String[] intents)
format Intents 
StringBuilder sb = new StringBuilder();
boolean first = true;
for (String intent : intents) {
    if (first) {
        first = false;
    } else {
        sb.append(' ');
    sb.append(intent);
return sb.toString();
StringformatInterval(long interval)
Returns human readable representation of interval value in days, hours etc. 
long days = interval / (24 * 60 * 60);
interval -= days * 24 * 60 * 60;
long hours = interval / (60 * 60);
interval -= hours * 60 * 60;
long minutes = interval / 60;
interval -= minutes * 60;
long seconds = interval;
StringBuffer buff = new StringBuffer();
...
StringformatIntoHHMMSS(int secsIn)
format Into HHMMSS 
int hours = secsIn / 3600, remainder = secsIn % 3600, minutes = remainder / 60, seconds = remainder % 60;
return ((hours < 10 ? "0" : "") + hours + ":" + (minutes < 10 ? "0" : "") + minutes + ":"
        + (seconds < 10 ? "0" : "") + seconds);
StringformatIntoHHMMSS(long l)
format Into HHMMSS 
long hours = l / 3600, remainder = l % 3600, minutes = remainder / 60, seconds = remainder % 60;
return ((hours < 10 ? "0" : "") + hours + "h" + (minutes < 10 ? "0" : "") + minutes + "m"
        + (seconds < 10 ? "0" : "") + seconds + "s");

Formats an array of ints. 
String res = "";
if (vals == null)
    res = "(null)";
else {
    res = "[";
    for (int ii = 0; ii < vals.length; ii++) {
        if (ii > 0)
            res += " ";

String valueStr = value + "";
int diff = length - valueStr.length();
StringBuilder strBuilder = new StringBuilder();
if (diff > 0) {
    while (diff > 0) {
        diff--;
        strBuilder.append(pad);
    strBuilder.append(valueStr);
    valueStr = strBuilder.toString();
return valueStr;
