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)); }} |
Output:
0
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)); }} |
Output:
-2
Program 3:
// 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("--09-06"); // Uses the function LocalDate dt2 = tm2.atYear(2018); // Prints the date System.out.println(dt1.compareTo(dt2)); }} |
Output:
1
