import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a Calendar object with specified date
    Calendar Cal = new GregorianCalendar(2015, 10, 25);

    //printing the Calendar
    System.out.println("The Calendar is: " + Cal.getTime());

    //printing the year
    System.out.println("The Year is: " + Cal.get(Calendar.YEAR));   

    //checking if the YEAR field has a value set
    System.out.println("The Year is set: " + Cal.isSet(Calendar.YEAR));  

    //clear the year
    Cal.clear(Calendar.YEAR);

    //checking if the YEAR field has a value set
    System.out.println("The Year is set: " + Cal.isSet(Calendar.YEAR));   
  }
}
