The computeTime() method in Calendar class is used for the conversion operation of the current calendar field values in fields[] to the millisecond time value time.
Syntax:
protected abstract void computeTime()
Parameters: The method does not take any parameters.
Return Value: The method does not return any value.
Below programs illustrate the working of computeTime() Method of Calendar class:
Example 1:
// Java Code to illustrate // computeTime() Method import java.util.*;
public class CalendarClassDemo
extends GregorianCalendar {
public static void main(String args[])
{
// Creating calendar object
CalendarClassDemo calndr = new CalendarClassDemo();
// Displaying the current date
System.out.println( "The Current "
+ "date is: " + calndr.getTime());
// Clearing the calendar
calndr.clear();
// Set a new year and call
// computeTime()
calndr.set(GregorianCalendar.YEAR, 2016 );
calndr.computeTime();
// Displaying the current date
System.out.println( "The recent"
+ " date is: " + calndr.getTime());
}
} |
Output:
The Current date is: Wed Feb 13 16:27:12 UTC 2019 The recent date is: Fri Jan 01 00:00:00 UTC 2016
Example 2:
// Java Code to illustrate // computeTime() Method import java.util.*;
public class CalendarClassDemo
extends GregorianCalendar {
public static void main(String args[])
{
// Creating calendar object
CalendarClassDemo calndr = new CalendarClassDemo();
// Displaying the current date
System.out.println( "The Current "
+ "date is: " + calndr.getTime());
// Clearing the calendar
calndr.clear();
// Set a new year and call
// computeTime()
calndr.set(GregorianCalendar.YEAR, 2000 );
calndr.computeTime();
// Displaying the current date
System.out.println( "The recent"
+ " date is: " + calndr.getTime());
}
} |
Output:
The Current date is: Wed Feb 13 16:27:15 UTC 2019 The recent date is: Sat Jan 01 00:00:00 UTC 2000
