Displaying date in a double digit format

Question

I am having trouble displaying the date in a double digit format. I want it to be so that when the day or the month is a single digit example: 4 It would display 04. I'm having trouble coming up with the logic for it, if somebody can help me I would be really grateful.

Calendar c = Calendar.getInstance();         int year = c.get(Calendar.YEAR);         int day = c.get(Calendar.DAY_OF_MONTH);         int month = c.get(Calendar.MONTH);          if (month % 10 == 0) {              Place = 0 + month;         }         String Dates = year + "-" + Place + "-" + day;         Date.setText((Dates)); 

Answer 1

DecimalFormat mFormat= new DecimalFormat("00"); mFormat.format(Double.valueOf(year)); 

in your case:

 mFormat.setRoundingMode(RoundingMode.DOWN);  String Dates =  mFormat.format(Double.valueOf(year)) + "-" +  mFormat.format(Double.valueOf(Place)) + "-" +  mFormat.format(Double.valueOf(day));
