Below programs illustrate the working of computeFields() Method of Calendar class:
Example 1:
import java.util.*;
public class CalendarClassDemo
extends GregorianCalendar {
public static void main(String args[])
{
CalendarClassDemo calndr = new CalendarClassDemo();
System.out.println( "The Current "
+ "date is: " + calndr.getTime());
calndr.clear();
calndr.set(GregorianCalendar.YEAR, 2016 );
calndr.computeFields();
System.out.println( "The recent"
+ " date is: " + calndr.getTime());
}
}

The Current date is: Wed Feb 13 16:15:15 UTC 2019
The recent date is: Wed Feb 13 16:15:15 UTC 2019

import java.util.*;
public class CalendarClassDemo
extends GregorianCalendar {
public static void main(String args[])
{
CalendarClassDemo calndr = new CalendarClassDemo();
System.out.println( "The Current "
+ "date is: " + calndr.getTime());
calndr.clear();
calndr.set(GregorianCalendar.YEAR, 2000 );
calndr.computeFields();
System.out.println( "The recent"
+ " date is: " + calndr.getTime());
}
}
