import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Get TemporalAdjuster with the
        // previousOrSame() of month adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters
                  .previousOrSame(
                      DayOfWeek.FRIDAY);
  
        // Using adjuster for local date-time
        LocalDate localDate
            = LocalDate.of(2020, 10, 30);
        LocalDate previousOrSameDOW
            = localDate.with(temporalAdjuster);
  
        // Print
        System.out.println(
            "Previous or same date "
            + "having FRIDAY for localdate "
            + localDate + " is: "
            + previousOrSameDOW);
    }
}
Output:
Previous or same date having FRIDAY for localdate 2020-10-30 is: 2020-10-30

Program 2:




// Java program to demonstrate
// TemporalAdjusters previousOrSame() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Get TemporalAdjuster with the
        // previousOrSame() day of week adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters
                  .previousOrSame(
                      DayOfWeek.THURSDAY);
  
        // Using adjuster for local date time
        LocalDate localDate
            = LocalDate.of(2018, 02, 23);
        LocalDate previousOrSameDOW
            = localDate.with(temporalAdjuster);
  
        // Print
        System.out.println(
            "Previous or same date "
            + "having THURSDAY for localdate "
            + localDate + " is: "
