Java – How to get current date time
1. Code Snippets
For java.util.Date, just create a new Date() DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); Date date = new Date(); System.out.println(dateFormat.format(date)); //2016/11/16 12:08:43For java.util.Calendar, uses Calendar.getInstance() DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); Calendar cal = Calendar.getInstance(); System.out.println(dateFormat.format(cal)); //2016/11/16 12:08:43For java.time.LocalDateTime, uses LocalDateTime.now() DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss"); LocalDateTime now = LocalDateTime.now(); System.out.println(dtf.format(now)); //2016/11/16 12:08:43For java.time.LocalDate, uses LocalDate.now() DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd"); LocalDate localDate = LocalDate.now(); System.out.println(dtf.format(localDate)); //2016/11/162. Full ExampleReview a full Java example to show you how to get the current date, time and display in a predefined format.
GetCurrentDateTime.java
package com.mkyong;
import java.text.DateFormat;
import java.text.SimpleDateFormat;import java.time.LocalDateTime;import java.time.format.DateTimeFormatter;import java.util.Calendar;import java.util.Date;public class GetCurrentDateTime {
private static final DateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
private static final DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss");public static void main(String[] args) {
Date date = new Date();
System.out.println(sdf.format(date));Calendar cal = Calendar.getInstance();
System.out.println(sdf.format(cal.getTime()));LocalDateTime now = LocalDateTime.now();
System.out.println(dtf.format(now));LocalDate localDate = LocalDate.now();
System.out.println(DateTimeFormatter.ofPattern("yyy/MM/dd").format(localDate));}
}
Output 2016/11/16 12:08:432016/11/16 12:08:432016/11/16 12:08:432016/11/16http://www.mkyong.com/java/java-how-to-get-current-date-time-date-and-calender/ http://www.mkyong.com/tutorials/java-date-time-tutorials/
