Method

StringformatNumber(int number)
insert commas to the given number for the readability 
StringBuilder s = new StringBuilder();
String intValue = Integer.toString(number);
final int len = intValue.length();
for (int i = 0; i < len; ++i) {
    s.append(intValue.charAt(i));
    int digit = len - i - 1;
    if (digit != 0 && (digit % 3 == 0)) {
        s.append(',');
...
StringformatNumber(int number, int zeros)
format Number 
String strZeros = repeatString("0", zeros);
String strNumber = Integer.toString(number);
return new StringBuilder().append(strZeros.substring(0, zeros - strNumber.length())).append(strNumber)
        .toString();
StringformatNumber(int theNumber, int theNumberOfDigits)
format Number

StringformatNumber(int value, int width, char c)
format Number 
String str = String.valueOf(value);
if (str.length() > width)

format Number 
return formatNumber(number, digits, '0');
StringformatNumber(long pNum, int pLen)
Formats a number with leading zeroes, to a specified length. 
StringBuilder result = new StringBuilder();
if (pNum >= Math.pow(10, pLen)) {
    throw new IllegalArgumentException(
            "The number to format cannot contain more digits than the length argument specifies!");
for (int i = pLen; i > 1; i--) {
    if (pNum < Math.pow(10, i - 1)) {
        result.append('0');
