How to parse Date from String in the format: dd/MM/yyyy to dd/MM/yyyy in java?
The java.text package provides a class named SimpleDateFormat which is used to format and parse dates in required manner (local).
One of the constructors of this class accepts a String value representing the desired date format and constructors SimpleDateFormat object.
The format() method of this class accepts a java.util.Date object and returns a date/time string in the format represented by the current object.
Therefore, to parse a date String to another date format −
Get the input date string.
Convert it into java.util.Date object.
Instantiate the SimpleDateFormat class by passing the desired (new) format as string to its constructor.
Invoke the format() method by passing the above obtained Date object as parameter.
Example
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;
}
}
}Output
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
