CalendarDemo.java

import java.util.Calendar;

public class CalendarDemo
{
    public static void main(String[] args)
    {
        Calendar cal1 = Calendar.getInstance();
        System.out.println("Current date = " + cal1.getTime());

        Calendar cal2 = Calendar.getInstance();
        cal2.set(Calendar.YEAR, 2030);
        System.out.println("future date  = " + cal2.getTime());

        /*
         * Parameters:
         *
         * anotherCalendar - the Calendar to be compared.
         *
         * Returns:
         *
         * the value 0 if the time represented by the argument is
         * equal to the time represented by this Calendar; a value
         * less than 0 if the time of this Calendar is before the time
         * represented by the argument; and a value greater than 0 if
         * the time of this Calendar is after the time represented by
         * the argument.
         */


        int result = cal1.compareTo(cal2);
        System.out.println("result = " + result);

    }
}

Output

Current date = Wed Jul 04 09:29:23 IST 2018
future date  = Thu Jul 04 09:29:24 IST 2030
result = -1
