Get the dd-MM-yyyy format of date in Java

Get the dd-MM-yyyy format of date in Java

In Java, you can format a date into the "dd-MM-yyyy" format using the java.time.LocalDate and java.time.format.DateTimeFormatter classes introduced in Java 8. Here's how you can achieve this:

Using java.time.LocalDate

import java.time.LocalDate; import java.time.format.DateTimeFormatter; public class DateFormatExample { public static void main(String[] args) { // Get the current date LocalDate currentDate = LocalDate.now(); // Define the date format pattern DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy"); // Format the date String formattedDate = currentDate.format(formatter); // Print the formatted date System.out.println("Formatted Date: " + formattedDate); } }

Explanation:

  1. LocalDate: Represents a date without time. LocalDate.now() gets the current date based on the system clock in the default time-zone.

  2. DateTimeFormatter: Used to define the format pattern for the date. DateTimeFormatter.ofPattern("dd-MM-yyyy") specifies that the date should be formatted as day-month-year.

  3. Formatting: The format method of LocalDate takes a DateTimeFormatter object and returns a formatted string representing the date in the specified pattern.

  4. Output: The output will be the current date formatted in the "dd-MM-yyyy" format, for example, "05-07-2024".

Handling Date Input

If you have a specific date that you want to format instead of the current date, you can create a LocalDate object from a string representation and then format it:

// Example with a specific date input String dateInput = "2024-07-05"; LocalDate specificDate = LocalDate.parse(dateInput); // Parse the date string String formattedSpecificDate = specificDate.format(formatter); // Format the date System.out.println("Formatted Specific Date: " + formattedSpecificDate);

Handling Legacy Date API (Pre-Java 8)

If you're using an older version of Java without java.time, you can use java.text.SimpleDateFormat from the legacy java.text package:

import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Date; public class LegacyDateFormatExample { public static void main(String[] args) { // Get the current date Date currentDate = new Date(); // Define the date format pattern DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy"); // Format the date String formattedDate = formatter.format(currentDate); // Print the formatted date System.out.println("Formatted Date: " + formattedDate); } }

However, it's recommended to use java.time.LocalDate for new development as it provides a more modern and thread-safe API for handling dates and times in Java applications.
