Java Get List of All LocalDate Between Two LocalDate

Tags: Java LocalDate

In this Java tutorial, we learn how to write Java program to get all days between two LocalDate objects, and return as a List of LocalDate objects in Java programming language.

How to get all days between two LocalDate in Java

In this first step, we create a new Java class named DateUtil, and implement a static method named getAllLocalDateBetween(LocalDate start, LocalDate end) to return a list of LocalDate objects between a start and an end LocalDate as Java code below.

DateUtil.java 

import java.time.LocalDate;
import java.util.ArrayList;
import java.util.List;

public class DateUtil {

    /**
     * Get List of LocalDate of all days between two LocalDate objects
     * @param start  the start LocalDate object
     * @param end the end LocalDate object
     * @return the List of all LocalDate between start and end LocalDate objects
     */
    public static List<LocalDate> getAllLocalDateBetween(LocalDate start, LocalDate end) {
        List<LocalDate> result = new ArrayList<>();
        while(start.isBefore(end)) {
            result.add(start);
            start = start.plusDays(1);
        }
        result.add(end);

        return result;
    }
}

In the following example Java program, we show how to use the DateUtil class above to get a list of days between 1 August 2022 to 5 August 2022.

GetAllLocalDateBetweenLocalDateExample.java 

import java.time.LocalDate;
import java.util.List;

public class GetAllLocalDateBetweenLocalDateExample {
    public static void main(String... args) {
        LocalDate startLocalDate = LocalDate.of(2022, 8, 1);
        LocalDate endLocalDate = LocalDate.of(2022, 8, 5);

        // Get List of All LocalDate Between Two LocalDate objects
        List<LocalDate> localDates = DateUtil.getAllLocalDateBetween(startLocalDate, endLocalDate);

        localDates.forEach(System.out::println);
    }
}
The output as below.
