How to get datepicker value in date format?

Question

I have a problem with my Datapicker

i use the code for getting date,month & year shown below

           DatePicker datePicker;
           datePicker = (DatePicker) findViewById(R.id.dateselect);

           int   day  = datePicker.getDayOfMonth();
           int   month= datePicker.getMonth() + 1;
           int   year = datePicker.getYear();

but when i print the date it shows the value 7 not 07 and for month it shows the value 2 not 02

I want these integer data in a date format ie; eg: 02-02-2013, 24-12-2013
Is there any possible way????

Answer 1

 public String checkDigit(int number)
    {
        return number<=9?"0"+number:String.valueOf(number);
    }

basic use:

month=checkDigit(month);
input 7
output 07
   String date=checkDigit(monthOfYear+1)+"/"+checkDigit(dayOfMonth)+"/"+year;
