Java LocalDate

The Java LocalDate class is an immutable and thread-safe class that represents a date with a default format of yyyy-MM-dd. The LocalDate class can be used to store a date in the following format “22nd April 2019”.

How to use

This class does not handle or represent a time or time-zone, we can use LocalDate class to store information like birthdays. Try the following examples to better understand –

Day example

Following is the simple example that shows how you add/subtract days in the current date and print them.

LocalDateDayExample.javaCopy
import java.time.LocalDate;

public class LocalDateDayExample {

    public static void main(String[] args) {

        LocalDate currentDate = LocalDate.now();

        // Get current date
        System.out.println("Today: " + currentDate);

        // Get yesterday's date (Subtract 1 day in current date)
        currentDate = LocalDate.now().minusDays(1);
        System.out.println("Yesterday: " + currentDate);

        // Get tommorow's date (Add 1 day in current date)
        currentDate = LocalDate.now().plusDays(1);
        System.out.println("Tommorow: " + currentDate);

    }
}

Month example

Following is the simple example that shows how you add/subtract months in the current month and print them.

LocalDateMonthExample.javaCopy
import java.time.LocalDate;

public class LocalDateMonthExample {

    public static void main(String[] args) {

        LocalDate currentDate = LocalDate.now();

        // Get current month
        System.out.println("Current month: " + currentDate.getMonth());

        // Previous month
        currentDate = LocalDate.now().minusMonths(1);
        System.out.println("Previous month: " + currentDate.getMonth());

        // Next month
        currentDate = LocalDate.now().plusMonths(1);
        System.out.println("Next month: " + currentDate.getMonth());

    }
}

Year example

Similar to the previous two examples, you also have the option to work with years. Following is the simple example that shows how you add/subtract years in the current year and print them.

LocalDateYearExample.javaCopy
import java.time.LocalDate;

public class LocalDateYearExample {

    public static void main(String[] args) {

        LocalDate currentDate = LocalDate.now();

        // Get current month
        System.out.println("Current year: " + currentDate.getYear());

        // Previous year
        currentDate = LocalDate.now().minusYears(1);
        System.out.println("Previous year: " + currentDate.getYear());

        // Next year
        currentDate = LocalDate.now().plusYears(1);
        System.out.println("Next year: " + currentDate.getYear());

    }
}

Leap or not example

Following is the example program to check if the given year is a leap year or not.

LocalDateLeapYear.javaCopy
import java.time.LocalDate;

public class LocalDateLeapYear {

    public static void main(String[] args) {

        // Check current year is leap year or not
        LocalDate localDate1 = LocalDate.now();
        System.out.println("Leap year: " + localDate1.isLeapYear());

        // Check given year is leap year or not
        LocalDate localDate2 = LocalDate.of(2012, 01, 01);
        System.out.println("Leap year: " + localDate2.isLeapYear());

    }
}
