Convert Multiple Date Format by Single Method #android #java #date

Create a method in a Global Class From where you can access this method in every class in Android(Java). 

public static String convertDateFormat(String inputFormat, String outPutFormat) {

List<SimpleDateFormat> knownPatterns = new ArrayList<SimpleDateFormat>();
knownPatterns.add(new SimpleDateFormat("dd/MM/yyyy"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd HH:MM:SS"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"));
DateFormat outputFormat = new SimpleDateFormat(outPutFormat);
Date date = null;
for (int i = 0; i < knownPatterns.size(); i++) {
try {
date = knownPatterns.get(i).parse(inputFormat);
} catch (ParseException e) {
e.printStackTrace();
}
}
return outputFormat.format(date);
}


As I have Created method convertDateFormat in Java class Utility.java as shown above.

Now Call this method in the main class where you want to format date

Utility.convertDateFormat(userProfile.getDateOfBirth(), "dd/MM/yyyy")

Now, here  Utility is java class where i have made method and i am calling that method in class where i want to convert Date Format.

Note:-where (userProfile.getDateOfBirth()) is input date which we want to convert and ( "dd/MM/yyyy") is output format date which you can give any format which is shown in method above.for another format which is not in method you can add that format in method.
