In Java, you can get the current date time via three classes – SimpleDateFormat, Date or Calender.

1. Date() + SimpleDateFormat()

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
System.out.println(dateFormat.format(date));

2. Calender() + SimpleDateFormat()

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar cal = Calendar.getInstance();
System.out.println(dateFormat.format(cal.getTime()));

Please visit this SimpleDateFormat documentation to understand the SimpleDateFormat in details.

Java Code example

Here is the full source code to show the use of date() and calender() to get the current date time.

package com.mkyong;
 
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
 
 
public class GetCurrentDateTime {
  public static void main(String[] args) {
 
	   DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
	   //get current date time with Date()
	   Date date = new Date();
	   System.out.println(dateFormat.format(date));
 
	   //get current date time with Calendar()
	   Calendar cal = Calendar.getInstance();
	   System.out.println(dateFormat.format(cal.getTime()));
 
  }
}
