TemporalAdjusters previous() method in Java with Examples

The previous(DayOfWeek) method of a TemporalAdjusters class is used to return a previous DayOfWeek TemporalAdjuster object which can be used to get a new Date object which is the previous 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 previous(DayOfWeek dayOfWeek)

Parameters: This method accepts dayOfWeek which can be used to get a new Date object which is the previous date with the same matching DayOfWeek. Return value: This method returns the previous day of the week adjuster. Below programs illustrate the TemporalAdjusters.previous() method: Program 1:

Java

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

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

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

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

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

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

Output:

Previous day of the week having WEDNESDAY for localdate 1998-10-31 is: 1998-10-28

Program 2:

Java

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

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

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

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

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

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

Output:

previous day of the week having THURSDAY for localdate 2029-12-11 is: 2029-12-06
