Below programs illustrate the TemporalAdjusters.previous() method:
Program 1:






// 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 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: "
