The compareTo() method of LocalDate class in Java method compares this date to another date.
Syntax:
public int compareTo(ChronoLocalDate other)
Parameter: This method accepts a parameter other which specifies the other date to compare to and it is not specifically null.
Return Value: It returns the comparator value which is negative if it is less else it is positive if it is greater.
Below programs illustrate the compareTo() method of LocalDate in Java:
Program 1:
// Program to illustrate the compareTo() method  import java.util.*;import java.time.*;  public class GfG {    public static void main(String[] args)    {        // First date        LocalDate dt = LocalDate.parse("2018-11-01");        System.out.println(dt);          // Second date        LocalDate dt1 = LocalDate.parse("2018-11-14");        System.out.println(dt1);          // Compare both dates        System.out.println(dt1.compareTo(dt));    }} |
Output:
2018-11-01 2018-11-14 13
Program 2:
// Program to illustrate the compareTo() method  import java.util.*;import java.time.*;  public class GfG {    public static void main(String[] args)    {        // First date        LocalDate dt = LocalDate.parse("2018-11-21");        System.out.println(dt);          // Second date        LocalDate dt1 = LocalDate.parse("2018-11-14");        System.out.println(dt1);          // Compare both dates        System.out.println(dt1.compareTo(dt));    }} |
Output:
2018-11-21 2018-11-14 -7
