TemporalAdjusters next() method in Java with Examples

The next(DayOfWeek) method of a TemporalAdjusters class is used to return a next day-of-week TemporalAdjuster object which can be used to get a new Date object which is the next date with the same matching DayOfWeek as passed as a parameter from any Date object on which this TemporalAdjuster is applied. Syntax:

public static TemporalAdjuster next(DayOfWeek dayOfWeek)

Parameters: This method accepts dayOfWeek which can be used to get a new Date object which is the next date with the same matching DayOfWeek. Return value: This method returns the next day of the week adjuster, not null. Below programs illustrate the TemporalAdjusters.next() method: Program 1:

Java

// Java program to demonstrate
// TemporalAdjusters.next()

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {

        // get TemporalAdjuster with
        // the next in month adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters.next(
                DayOfWeek.WEDNESDAY);

        // using adjuster for local date time
        LocalDate localDate
            = LocalDate.of(1998, 10, 31);
        LocalDate nextDOW
            = localDate.with(temporalAdjuster);

        // print
        System.out.println(
            "next day of the week having"
            + " WEDNESDAY for localdate "
            + localDate + " is: "
            + nextDOW);
    }
}

Output:

next day of the week having WEDNESDAY for localdate 1998-10-31 is: 1998-11-04

Program 2:

Java

// Java program to demonstrate
// TemporalAdjusters.next() method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {

        // get TemporalAdjuster with the
        // next day of week adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters.next(
                DayOfWeek.THURSDAY);

        // using adjuster for local date time
        LocalDate localDate
            = LocalDate.of(2029, 12, 11);
        LocalDate nextDOW
            = localDate.with(temporalAdjuster);

        // print
        System.out.println(
            "next day of the week having"
            + " THURSDAY for localdate "
            + localDate + " is: "
            + nextDOW);
    }
}

Output:

next day of the week having THURSDAY for localdate 2029-12-11 is: 2029-12-13
