Parameters: This method accepts nothing.
Return value: This method returns the first day of next year adjuster, not null.
Below programs illustrate the TemporalAdjusters.firstDayOfNextYear() method:
Program 1:
// Java program to demonstrate// TemporalAdjusters.firstDayOfNextYear() import java.time.LocalDate;import java.time.temporal.*; public class GFG { public static void main(String[] args) { // get TemporalAdjuster with first day // of next year adjuster TemporalAdjuster temporalAdjuster = TemporalAdjusters.firstDayOfNextYear(); // using adjuster for local date-time LocalDate localDate = LocalDate.of(2020, 05, 11); LocalDate firstDayOfNextYear = localDate.with(temporalAdjuster); // print System.out.println("First day of next " + "year for localdate " + localDate +": " + firstDayOfNextYear); }} |
Output:
First day of next year for localdate 2020-05-11: 2021-01-01
Program 2:
// Java program to demonstrate// TemporalAdjusters.firstDayOfNextYear() method import java.time.LocalDate;import java.time.temporal.TemporalAdjuster;import java.time.temporal.TemporalAdjusters; public class GFG { public static void main(String[] args) { // get TemporalAdjuster with first day // of next year adjuster TemporalAdjuster temporalAdjuster = TemporalAdjusters .firstDayOfNextYear(); // using adjuster for local date-time LocalDate localDate = LocalDate.of(2010, 12, 29); LocalDate firstDayOfNextYear = localDate.with(temporalAdjuster); // print System.out.println("First day of next " + "year for localdate :" + localDate +": " + firstDayOfNextYear); }} |
Output:
First day of next year for localdate :2010-12-29: 2011-01-01
