Java

// Java program to demonstrate
// MonthDay.isValidYear() method

import java.time.*;
import java.time.temporal.ChronoField;

public class GFG {
    public static void main(String[] args)
    {
        // create a MonthDay object
        MonthDay month = MonthDay.parse("--10-12");

        // apply isValidYear() method
        boolean value = month.isValidYear(2012);

        // print result
        System.out.println("Year 2012 is valid for monthday: "
                           + month + " = " + value);
    }
}

Output:

Year 2012 is valid for monthday: --10-12 = true

Program 2:

Java

// Java program to demonstrate
// MonthDay.isValidYear() method

import java.time.*;
import java.time.temporal.ChronoField;

public class GFG {
    public static void main(String[] args)
    {
        // create a MonthDay object
        MonthDay month = MonthDay.parse("--02-29");

        // apply isValidYear() method
        boolean value = month.isValidYear(2017);

        // print result
        System.out.println("Year 2017 is valid for monthday: "
                           + month + " = " + value);
