GregorianCalendar is a concrete implementation of a Calendar for Gregorian calendar.


GregorianCalendar(int year, int month, int dayOfMonth) 
GregorianCalendar(int year, int month, int dayOfMonth, int hours, int minutes) 
GregorianCalendar(int year, int month, int dayOfMonth, int hours, int minutes, int seconds)

The following constructors create objects initialized with the current date and time using the specified time zone and/or locale:


GregorianCalendar(Locale locale) 
GregorianCalendar(TimeZone timeZone) 
GregorianCalendar(TimeZone timeZone, Locale locale)

isLeapYear( ) method frolm the GregorianCalendar class tests if the year is a leap year.


boolean isLeapYear(int year)

 
import java.util.Calendar;
import java.util.GregorianCalendar;

public class Main {
  public static void main(String args[]) {
    String months[] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};
    int year;
    // Create a Gregorian calendar initialized
    // with the current date and time in the
    // default locale and timezone.
    GregorianCalendar gcalendar = new GregorianCalendar();

    // Display current time and date information.
    System.out.print("Date: ");
    System.out.print(months[gcalendar.get(Calendar.MONTH)]);
    System.out.print(" " + gcalendar.get(Calendar.DATE) + " ");
    System.out.println(year = gcalendar.get(Calendar.YEAR));

    System.out.print("Time: ");
    System.out.print(gcalendar.get(Calendar.HOUR) + ":");
    System.out.print(gcalendar.get(Calendar.MINUTE) + ":");
    System.out.println(gcalendar.get(Calendar.SECOND));

    // Test if the current year is a leap year
    if (gcalendar.isLeapYear(year)) {
      System.out.println("The current year is a leap year");
    } else {
      System.out.println("The current year is not a leap year");
    }
  }
}
