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
