NumberFormatter class contains static utility methods for formatting Numbers. Now, there is a mere method defined. The method addLeadingZero “Formats a number to include a leading zero if it is a single digit between -1 and 10.” , simple but very useful. 
I found codes “returnString+=NumberUtil.addLeadingZero(dateToFormat.getDate());” from internet. We can see that this is what we need when we do such things, to format year, month, day, hour, minute, second or others whatever.
