public final class LocalDate extends Object
A date without a time-zone in the ISO-8601 calendar system, such as 2007-12-03.
public class Date extends Object
The class Date represents a specific instant in time, with millisecond precision.
public abstract class Clock extends Object
A clock providing access to the current instant, date and time using a time-zone.
public static Clock systemUTC()
Obtains a clock that returns the current instant using the best available system clock, converting to date and time using the UTC time-zone.
This clock, rather than systemDefaultZone(), should be used when you need the current instant without the date or time.
package com.candidjava.datetime;
import java.time.Clock;
import java.time.LocalDateTime;
import java.util.Calendar;
import java.util.Date;
public class GetCurrentDateAndTime {
public static void main(String[] args) {
// Using LocalDateTime Class
LocalDateTime datetime = LocalDateTime.now();
System.out.println("Current Date and Time Using LocalDateTime Class:");
System.out.println(datetime);
System.out.println("-------------------------------------------------");
// Using Util Date Class
Date date = new Date();
System.out.println("Current Date and Time Using Util Date Class:");
System.out.println(date);
System.out.println("-------------------------------------------------");
// Using Clock class
System.out.println("Current Date and Time Using Clock Class:");
System.out.println(Clock.systemUTC().instant());
System.out.println("-------------------------------------------------");
// Using Calendar Class
Date datecalendar = Calendar.getInstance().getTime();
System.out.println("Current Date and Time Using Calendar Class:");
System.out.println(datecalendar);
System.out.println("-------------------------------------------------");
}
}
