The format() method of DateFormat class in Java is used to format a given Date object into a string representing Date/Time.
Syntax:
String format(Date date)
Parameters: This method accepts a single parameter date which is a Date object.
Return Value: This method returns a String which is the formatted date-time value of the Date object passed as a parameter to the method.
The below programs illustrate the above method:
Program 1:
Java
// Java program to illustrate the// format() methodimport java.text.DateFormat;import java.util.Date;public class GFG { public static void main(String[] args) { // Create a Date instance Date currentDate = new Date(); // Create a DateFormat instance and format // current Date String dateToStr = DateFormat.getInstance() .format(currentDate); System.out.println("Formatted Date String: " + dateToStr); }} |
Output:
Formatted Date String: 2/27/19 3:31 PM
Time complexity: O(1)
Auxiliary space: O(1)
Program 2:
Java
// Java program to illustrate the// format() methodimport java.text.DateFormat;import java.util.*;public class GFG { public static void main(String[] args) { // Create a Date instance Date date = new Date(2323223232L); // Create a DateFormat instance and format // the specified Date String dateToStr = DateFormat.getInstance() .format(date); System.out.println("Formatted Date String: " + dateToStr); }} |
Output:
Formatted Date String: 1/27/70 9:20 PM
Time complexity: O(1)
Auxiliary space: O(1)
