How do I manipulate LocalDate object using TemporalAdjuster?

In the previous example we manipulate the value of LocalDate by adding or subtracting the value of date object by days, months, years using methods like plusMonths() or minusDays(). Or by changing the year or the month of the date object using methods like withYear() or withMonth().

But there are times that we want to manipulate the date object so that we can get the first day of the month or the last day of the month. We want to manipulate the date value to advance the date to the first Monday after the current day or the last the of the year.

To manipulate the date object in this way we can use the with() method and pass a TemporalAdjuster object as an argument. Fortunately, the Date and Time API already provide some commonly used TemporalAdjuster. These TemporalAdjuster are provided as a static factory methods that we can find in the java.time.temporal.TemporalAdjusters class.

The following example is a code snippet to manipulate the date object using TemporalAdjuster / TemporalAdjusters class.

package org.kodejava.example.datetime;

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.temporal.TemporalAdjusters;

public class DateManipulationWithTemporalAdjuster {
    public static void main(String[] args) {
        LocalDate date =;
        System.out.println("Current date       = " + date);

        LocalDate date1 = date.with(TemporalAdjusters.firstDayOfMonth());
        System.out.println("First day of month = " + date1);

        LocalDate date2 = date.with(TemporalAdjusters.lastDayOfMonth());
        System.out.println("Last day of month  = " + date2);

        LocalDate date3 = date.with(;
        System.out.println("Next Monday        = " + date3);

        LocalDate date4 = date.with(TemporalAdjusters.lastDayOfYear());
        System.out.println("Last day of year   = " + date4);

The result of the code snippet are:

Current date       = 2016-03-06
First day of month = 2016-03-01
Last day of month  = 2016-03-31
Next Monday        = 2016-03-07
Last day of year   = 2016-12-31

The table below shows the complete of static factory method provided by the TemporalAdjusters class.

Method Name Method Description
dayOfWeekInMonth Returns a new date in the same month with the ordinal day-of-week.
firstDayOfMonth Returns a new date set to the first day of the current month.
firstDayOfNextMonth Returns a new date set to the first day of the next month.

lastInMonth Returns a new date in the same month with the last matching day-of-week.
next Returns the next day-of-week adjuster.
nextOrSame Returns the next-or-same day-of-week adjuster.
ofDateAdjuster Returns user-written adjuster.
previous Returns the previous day-of-week adjuster.
previousOrSame Returns the previous-or-same day-of-week adjuster.

How do I manipulate the value of LocalDate object?

In the following example we will learn how to manipulate a LocalDate object. There are many methods available for us to change the value of a LocalDate object. For example we can change the year, month and day of LocalDate object. We can use methods like withYear(), withDayOfMonth(), plusYears(), minusMonths(), etc. All these methods will return a new LocalDate object, the original LocalDate will stay unchanged.

Let’s see the following code example for demonstration on how to manipulate the value of LocalDate object.

package org.kodejava.example.datetime;

import java.time.LocalDate;
import java.time.Month;
import java.time.temporal.ChronoField;
import java.time.temporal.ChronoUnit;

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

    private static void relativeAttributeManipulations() {
        LocalDate date1 = LocalDate.of(2015, Month.AUGUST, 17);
        LocalDate date2 = date1.minusYears(70);
        LocalDate date3 = date2.plusMonths(10);
        LocalDate date4 = date3.minusDays(15);
        LocalDate date5 = date4.plusWeeks(52);
        LocalDate date6 = date5.minus(52, ChronoUnit.WEEKS);

        System.out.println("of(2015, Month.AUGUST, 17)        => " + date1);
        System.out.println("date1.minusYears(70)              => " + date2);
        System.out.println("date1.plusMonths(10)              => " + date3);
        System.out.println("date3.minusDays(15)               => " + date4);
        System.out.println("date4.plusWeeks(52)               => " + date5);
        System.out.println("date5.minus(52, ChronoUnit.WEEKS) => " + date6);


    private static void absoluteAttributeManipulations() {
        LocalDate date1 = LocalDate.of(2016, Month.JANUARY, 1);
        LocalDate date2 = date1.withYear(2010);
        LocalDate date3 = date2.withMonth(Month.DECEMBER.getValue());
        LocalDate date4 = date3.withDayOfMonth(15);
        LocalDate date5 = date4.with(ChronoField.DAY_OF_YEAR, 100);

        System.out.println("of(2016, Month.JANUARY, 1)                 => " + date1);
        System.out.println("date1.withYear(2010)                       => " + date2);
        System.out.println("date2.withMonth(Month.DECEMBER.getValue()) => " + date3);
        System.out.println("date3.withDayOfMonth(15)                   => " + date4);
        System.out.println("date4.with(ChronoField.DAY_OF_YEAR, 100)   => " + date5);

The results of this code snippet are:

of(2016, Month.JANUARY, 1)                 => 2016-01-01
date1.withYear(2010)                       => 2010-01-01
date2.withMonth(Month.DECEMBER.getValue()) => 2010-12-01
date3.withDayOfMonth(15)                   => 2010-12-15
date4.with(ChronoField.DAY_OF_YEAR, 100)   => 2010-04-10

of(2015, Month.AUGUST, 17)        => 2015-08-17
date1.minusYears(70)              => 1945-08-17
date1.plusMonths(10)              => 1946-06-17
date3.minusDays(15)               => 1946-06-02
date4.plusWeeks(52)               => 1947-06-01
date5.minus(52, ChronoUnit.WEEKS) => 1946-06-02
