Take int of day, month, year and convert to DD/MM/YYYY

Question

I am writing a method to take a DOB of 3 integers - day, month, year and return the formatted version DD/MM/YYYY.

I am currently using dateFormatter and simple date form

Answer 1

Why use formatter? just do this:

   public String DateOfBirth(int day, int month, int year) 
{
    String DOB = day + "/" + month + "/" + year;

    return DOB;
}

If it's for an assignment, the teacher probably wants you to not use formatter.

Also, as someone else mentioned: If you are trying to concatenate integers as a string you need some string in between. Otherwise you are summing the values of the integers.
