The compareTo() method of MonthDay class in Java compares this month-day to another month-day.
Syntax:
public int compareTo(MonthDay other)
Parameter: This method accepts a parameter other which specifies the other month-day to compare to and not null.
Returns: The function returns the comparator value. It can be negative if it is less or positive if it is greater.
Exceptions: The function throws an NullPointerException if the other is null.
Below programs illustrate the MonthDay.compareTo() method:
Program 1:
// Program to illustrate the compareTo() method import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// Parses the date
MonthDay tm1 = MonthDay.parse( "--12-06" );
// Uses the function
LocalDate dt1 = tm1.atYear( 2018 );
// Parses the date
MonthDay tm2 = MonthDay.parse( "--12-06" );
// Uses the function
LocalDate dt2 = tm2.atYear( 2018 );
// Prints the date
System.out.println(dt1.compareTo(dt2));
}

Program 2:
// Program to illustrate the compareTo() method import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// Parses the date
MonthDay tm1 = MonthDay.parse( "--10-06" );
// Uses the function
LocalDate dt1 = tm1.atYear( 2018 );
// Parses the date
MonthDay tm2 = MonthDay.parse( "--12-06" );
// Uses the function
LocalDate dt2 = tm2.atYear( 2018 );
// Prints the date
System.out.println(dt1.compareTo(dt2));

public class GfG {
public static void main(String[] args)
{
// Parses the date
MonthDay tm1 = MonthDay.parse( "--10-06" );
// Uses the function
LocalDate dt1 = tm1.atYear( 2018 );
// Parses the date
MonthDay tm2 = MonthDay.parse( "--09-06" );
// Uses the function
LocalDate dt2 = tm2.atYear( 2018 );
// Prints the date
System.out.println(dt1.compareTo(dt2));
