The java.text package provides a class called SimpleDateFormat for formatting and parsing dates in the desired way (natively).
One of the constructors of this class accepts a string value representing the desired date format and a constructor SimpleDateFormat object.
The format() method of this class accepts a java.util.Date object and returns the date/time character in the format represented by the current object string.
So, parse the date string into another date format -
Get the input date string.
Convert it to a java.util.Date object.
>Instantiate the SimpleDateFormat class by passing the desired (new) format as a string to its constructor.
Call the format() method by passing the Date object obtained above as a parameter.
Live demonstration
import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Scanner; public class FormattingDate { public static Date StringToDate(String dob) throws ParseException { //Instantiating the SimpleDateFormat class SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy"); //Parsing the given String to Date object Date date = formatter.parse(dob); System.out.println("Date object value: "+date); return date; } public static void main(String args[]) throws ParseException { //Reading name and date of birth from the user Scanner sc = new Scanner(System.in); System.out.println("Enter your name: "); String name = sc.next(); System.out.println("Enter your date of birth (dd-MM-yyyy): "); String dob = sc.next(); //Converting String to Date Date date = FormattingDate.StringToDate(dob); System.out.println("Select format: "); System.out.println("a: MM-dd-yyyy || b: dd-MM-yyyy || c: yyyy-MM-dd "); char ch = sc.next().toCharArray()[0];; switch (ch) { case 'a': System.out.println("Date in the format: MM-dd-yyyy"); System.out.println(new SimpleDateFormat("MM-dd-yyyy").format(date)); break; case 'b': System.out.println("Date in in the format: dd-MM-yyyy"); System.out.println(new SimpleDateFormat("dd-MM-yyyy").format(date)); break; case 'c': System.out.println("Date in the format: yyyy-MM-dd"); System.out.println(new SimpleDateFormat("yyyy-MM-dd").format(date)); break; default: System.out.println("Model not found"); break; } } }
Enter your name: Krishna Enter your date of birth (dd-MM-yyyy): 26-09-1989 Date object value: Tue Sep 26 00:00:00 IST 1989 Select format: a: MM-dd-yyyy || b: dd-MM-yyyy || c: yyyy-MM-dd a Date in the format: MM-dd-yyyy 09-26-1989
