Formatting Global Dates in Java

Formatting Global Dates in Java

Dates are an important part of all record keeping activities. Due to globalization, it is important to understand how each country represents the date. Some countries start the date with Year, some with Month and some of them interchange Month and Date place holders. Formatting (using ofPattern() method) is a powerful utility that easily helps users overcome this problem.

import java.time.LocalDateTime;import java.time.format.DateTimeFormatter;public class TimeFormats {public static void main(String args[]) { LocalDateTime localDateTime =; System.out.println("Default format: " + localDateTime); //Formatting DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy HH:mm:ss"); String formattedDate = localDateTime.format(dateTimeFormatter); System.out.println("After formatting (dd-MMM-yyyy HH:mm:ss): " + formattedDate); //Additonal Formatting dateTimeFormatter = DateTimeFormatter.ofPattern("E, MMM dd yyyy"); formattedDate = localDateTime.format(dateTimeFormatter); System.out.println("After formatting (E, MMM dd yyyy): " + formattedDate); } }

Expected output:

[root@mypc]# java TimeFormatsDefault format: 2018-11-27T16:40:07.893After formatting (dd-MMM-yyyy HH:mm:ss): 27-Nov-2018 16:40:07After formatting (E, MMM dd yyyy): Tue, Nov 27 2018
