Java Time API

Comment

It has always been hard to work with Date, Time, and Time Zones in java. There was no standard approach or API in java for date and time in Java. One of the nice addition in Java 8 is the java.time package that will streamline the process of working with time in java.

Just by looking at Java Time API packages, I can sense that they will be very easy to use. It has some sub-packages java.time.format that provides classes to print and parse dates and times and java.time.zone provides support for time zones and their rules.

The new Time API prefers enums over integer constants for months and days of the week. One of the useful classes is DateTimeFormatter for converting DateTime objects to strings

package com.journaldev.java8.time;

import java.time.LocalDate;
import java.time.Month;
import java.time.ZoneId;

/**
 * LocalDate Examples
 * @author pankaj
 *
 */
public class LocalDateExample {

	public static void main(String[] args) {
		
		//Current Date
		LocalDate today = LocalDate.now();
		System.out.println("Current Date="+today);
		
		//Creating LocalDate by providing input arguments
		LocalDate firstDay_2014 = LocalDate.of(2014, Month.JANUARY, 1);
		System.out.println("Specific Date="+firstDay_2014);
		
	
		LocalDate todayKolkata = LocalDate.now(ZoneId.of("Asia/Kolkata"));
		System.out.println("Current Date in IST="+todayKolkata);

		
		LocalDate dateFromBase = LocalDate.ofEpochDay(365);
		System.out.println("365th day from base date= "+dateFromBase);
		
		LocalDate hundredDay2014 = LocalDate.ofYearDay(2014, 100);
		System.out.println("100th day of 2014="+hundredDay2014);
	}

}
