CalendarDemo.java

import java.util.Calendar;

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

        /*
         * Parameters:
         *
         * field - the calendar field.
         *
         * amount - the amount of date or time to be added to the field.
         */

       
        // subtract 3 months from the calendar
        cal.add(Calendar.MONTH, -3);
        System.out.println("3 months ago        = " + cal.getTime());

        // subtract 10 years from the calendar
        cal.add(Calendar.YEAR, -10);
        System.out.println("10 years ago        = " + cal.getTime());
    }
}

Output

The current date is = Sat Jun 30 09:07:01 IST 2018
3 months ago        = Fri Mar 30 09:07:01 IST 2018
10 years ago        = Sun Mar 30 09:07:01 IST 2008
