Firebase - retrieving data from a date

Question

I want to retrieve data from a particular date from Firebase . They are stored in the following format:

I am using a datePicker to choose a date. But I am not able to figure out how I can change the date chosen to the above format.

For example: I choose a date say 28th March 2018 . I would use the code:

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

But I am not able to figure out how to change it to the following format, Wed Mar 28 2018 00:00:00 GMT+530 (IST)

Answer 1

After spending hours, trying to figure out a way, I have finally found a solution and have realized that this was a pretty silly question to ask. Nevertheless, this is what I have come up with,

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

try {
     SimpleDateFormat sdf = new SimpleDateFormat("d-M-yyyy");
     Date date = sdf.parse(day + "-" + month + "-" + year);

     sdf = new SimpleDateFormat("EEE MMM dd yyyy");
     String strDate = sdf.format(date) + " 00:00:00 GMT+0530 (IST)";

     Log.d("date_simple", strDate);

} catch (ParseException e) {
     Log.d("date_simple", e + "");
     e.printStackTrace();
}
