The firstDayOfNextMonth() method of a TemporalAdjusters class is used to return the “first day of next month” TemporalAdjuster object, which returns a new Date object set to the first day of the next month. Syntax:
public static TemporalAdjuster firstDayOfNextMonth()
Parameters: This method accepts nothing. Return value: This method returns the first day of next month adjuster, not null. Below programs illustrate the TemporalAdjusters.firstDayOfNextMonth() method: Program 1:
Java
// Java program to demonstrate// TemporalAdjusters.firstDayOfNextMonth()import java.time.LocalDate;import java.time.temporal.TemporalAdjusters;import java.time.temporal.TemporalAdjusters;public class GFG { public static void main(String[] args) { // get TemporalAdjuster with first day // of next month adjuster TemporalAdjuster temporalAdjuster = TemporalAdjusters.firstDayOfNextMonth(); // using adjuster for local date time LocalDate localDate = LocalDate.of(2020, 05, 11); LocalDate firstDayOfNextMonth = localDate.with(temporalAdjuster); // print System.out.println("First day of next " + "month for localdate " + localDate + ": " + firstDayOfNextMonth); }} |
Output:
First day of next month for localdate 2020-05-11: 2020-06-01
Program 2:
Java
// Java program to demonstrate// TemporalAdjusters.firstDayOfNextMonth() methodimport java.time.LocalDate;import java.time.temporal.*;public class GFG { public static void main(String[] args) { // get TemporalAdjuster with first day // of next month adjuster TemporalAdjuster temporalAdjuster = TemporalAdjusters .firstDayOfNextMonth(); // using adjuster for local date-time LocalDate localDate = LocalDate.of(2010, 12, 29); LocalDate firstDayOfNextMonth = localDate.with(temporalAdjuster); // print System.out.println( "First day of next " + "month for localdate " + localDate + ": " + firstDayOfNextMonth); }} |
Output:
First day of next month for localdate 2010-12-29: 2011-01-01
