Java 8 Date parsing and formatting example.


Java 8 date and time API makes date formatting and parsing very simple. This page gives many examples on parsing and formatting date.

DateParsingFormatEx
package com.java2novice.datetime;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.Month;
import java.time.format.DateTimeFormatter;
import java.util.Locale;

public class DateParsingFormatEx {

	public static void main(String[] args) {

		// create a date time object (2016-01-01 10:30)
		LocalDateTime dtObj = LocalDateTime.of(2016, Month.JANUARY, 1, 10, 35);
		System.out.println("date time obj: "+dtObj);

		// format ISO date time (2016-01-01T10:35:00)
		String isoObj = dtObj.format(DateTimeFormatter.ISO_DATE_TIME);
		System.out.println("date time obj in ISO format: "+isoObj);

		// format basic ISO date format (20160101)
		String basicIsoObj = dtObj.format(DateTimeFormatter.BASIC_ISO_DATE);
		System.out.println("date time obj in basic ISO format: "+basicIsoObj);

		// format as ISO week date (2015-W53-5)
		String isoWeekObj = dtObj.format(DateTimeFormatter.ISO_WEEK_DATE);
		System.out.println("date time obj in ISO week format: "+isoWeekObj);

		// french date formatting (1. janvier 2016)
		String frenchDate = dtObj.format(DateTimeFormatter.ofPattern("d. MMMM yyyy", new Locale("fr")));
		System.out.println("date time obj in french date format: "+frenchDate);

		// user custom pattern (01/01/16)
		String custDtObj = dtObj.format(DateTimeFormatter.ofPattern("dd/MM/yy"));
		System.out.println("date time obj in custom format: "+custDtObj);


		// parsing string to date object
		LocalDate isoDateObj = LocalDate.parse("2016-02-22");
		System.out.println("iso date: "+isoDateObj);

		// custom date string to date object
		LocalDate custPatternObj = LocalDate.parse("02-2016-22", DateTimeFormatter.ofPattern("MM-yyyy-dd"));
		System.out.println("custom date format: "+custPatternObj);
	}
}

Output:
date time obj: 2016-01-01T10:35
date time obj in ISO format: 2016-01-01T10:35:00
date time obj in basic ISO format: 20160101
date time obj in ISO week format: 2015-W53-5
date time obj in french date format: 1. janvier 2016
date time obj in custom format: 01/01/16
iso date: 2016-02-22
custom date format: 2016-02-22
