The complete() method in Calendar class is used to fill any unset fields of the calendar fields. It follows the following process of completion:
- At first, if the time value has not been calculated, the computeTime() method is called to calculate it from calendar field values.
- Second, to calculate all the calendar field values the computeFields() method is used.
Syntax:
protected void complete()
Parameters: The method does not take any parameters.
Return Value: The method does not return any value.
Below programs illustrate the working of complete() Method of Calendar class:
Example 1:
// Java Code to illustrate// complete() 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 // complete() calndr.set(GregorianCalendar.YEAR, 2008); calndr.complete(); // Displaying the current date System.out.println("The new" + " date is: " + calndr.getTime()); }} |
Output:
The Current date is: Wed Feb 13 15:39:33 UTC 2019 The new date is: Tue Jan 01 00:00:00 UTC 2008
Example 2:
// Java Code to illustrate// complete() 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 // complete() calndr.set(GregorianCalendar.YEAR, 1996); calndr.complete(); // Displaying the current date System.out.println("The new" + " date is: " + calndr.getTime()); }} |
Output:
The Current date is: Wed Feb 13 15:39:36 UTC 2019 The new date is: Mon Jan 01 00:00:00 UTC 1996
