Java compare localdate: In this article we are going to see the use of Java LocalDate class compareTo( ) method with suitable examples.

Java LocalDate compareTo( ) Method with Example

This java.time.LocalDate.compareTo(ChronoLocalDate other) method is used to compare a date with another date. It returns comparator value, gives negative if less, positive if greater.

Syntax:

public int compareTo(ChronoLocalDate other)

Where,

  • other refers to the other date to be compared.

Let’s see a program to understand it more clearly.

Approach:

  • Create two objects of LocalDate class which will hold the parsed dates, here we have taken date1 and date2.
  • Then by using compareTo() method compare two dates like date2.compareTo(date1)
  • Print the final result.

Program:(CASE-1: When the second date is greater than first date)

import java.time.LocalDate;

public class Main
{
    public static void main(String[] args) 
    {
        //Create an object of LocalDate class and assign a date to it
     	LocalDate date1 = LocalDate.parse("2022-04-25");
      	System.out.println("date-1: "+date1);
      	//Create an object of LocalDate class and assign a date to it
    	LocalDate date2 = LocalDate.parse("2022-05-08");
      	System.out.println("date-2: "+date2);
      	//Pass both the date into method and compare both the values and print the final result
        //it will return positive value as date2 is greater than date1
      	System.out.println("Compared value: "+date2.compareTo(date1));  
   	}
}

Output:

date-1: 2022-04-25
date-2: 2022-05-08
Compared value: 1

Program:(CASE-2: When the second date is less than first date)

import java.time.LocalDate;

public class Main
{
    public static void main(String[] args) 
    {
        //Create an object of LocalDate class and assign a date to it
         LocalDate date1 = LocalDate.parse("2022-04-25");
          System.out.println("date-1: "+date1);
          //Create an object of LocalDate class and assign a date to it
        LocalDate date2 = LocalDate.parse("2022-05-08");
          System.out.println("date-2: "+date2);
          //Pass both the date into method and compare both the values and print the final result
          //it will return positive value as date1 is less than date2
          System.out.println("Compared value: "+date1.compareTo(date2));  
       }
}
Output:

date-1: 2022-04-25
date-2: 2022-05-08
Compared value: -1
