Displaying date in a double digit format

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 comming up with the logic for it, if somebody can help me I would be really greatful. Thanks in Advanced

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));
