TemporalAdjusters

Description

TemporalAdjusters defines some useful methods we can use to adjust date.

• next(DayOfWeek dayOfWeek)
• nextOrSame(DayOfWeek dayOfWeek)
• previous(DayOfWeek dayOfWeek)
• previousOrSame(DayOfWeek dayOfWeek)
• firstInMonth(DayOfWeek dayOfWeek)
• lastInMonth(DayOfWeek dayOfWeek)
• dayOfWeekInMonth(int ordinal, DayOfWeek dayOfWeek)
• firstDayOfMonth()
• lastDayOfMonth()
• firstDayOfYear()
• lastDayOfYear()
• firstDayOfNextMonth()
• firstDayOfNextYear()
• ofDateAdjuster(UnaryOperator<LocalDate> dateBasedAdjuster)

Example

The following code shows how to use dayOfWeekInMonth.

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.Month;
import java.time.temporal.TemporalAdjusters;
//w ww  .jav  a2  s.co  m
public class Main {

  public static void main(String[] args) {
    LocalDate ld1  = LocalDate.of(2014, Month.MAY,  21);
    System.out.println(ld1);
    LocalDate ld2  = ld1.with(TemporalAdjusters.dayOfWeekInMonth(5, DayOfWeek.SUNDAY));
    System.out.println(ld2);
  }
}

The code above generates the following result.
