Date Time Adjuster

Description

We may want to adjust a date and time to the first Monday of the month, or the next Tuesday.

We can adjust date and time using TemporalAdjuster interface. The interface has one method, adjustInto(), which takes a Temporal and returns a Temporal.

TemporalAdjusters class contains static methods that return different types of predefined date adjusters.

Example

The following code shows how to compute the first Monday after January 1, 2014:

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.Month;
import java.time.temporal.TemporalAdjusters;
//from w w  w . j  av a2 s. c o m
public class Main {

  public static void main(String[] args) {
    LocalDate ld1  = LocalDate.of(2014, Month.JANUARY,  1);
    LocalDate ld2  = ld1.with(TemporalAdjusters.next(DayOfWeek.MONDAY)); 
    System.out.println(ld1);
    System.out.println(ld2);

  }
}

The code above generates the following result.
