GregorianCalendarDemo.java

import java.util.GregorianCalendar;

public class GregorianCalendarDemo
{
    public static void main(String[] args)
    {
        GregorianCalendar cal = (GregorianCalendar) GregorianCalendar
                .getInstance();

        /*
         * Parameters:
         *
         * field - the given calendar field.
         *
         * Returns:
         *
         * the value for the given calendar field.
         */

        int year = cal.get(GregorianCalendar.YEAR);
        boolean isLeapYear = cal.isLeapYear(year);
        System.out.println(year + " is leap year = " + isLeapYear);

        isLeapYear = cal.isLeapYear(2020);
        System.out.println("2020 Is leap year = " + isLeapYear);
    }
}

Output

2018 is leap year = false
2020 Is leap year = true
