The clear() method in Calendar class is used to set all the calendar field values and the time value of this Calendar undefined.
Note: Implementation of calendar class may use default field values for date and time calculations.
Syntax:
public final void clear()
Parameters: The method does not take any parameters.
Return Value: The method does not return any value.
Below programs illustrate the working of clear() Method of Calendar class:
Example:
// Java Code to illustrate clear() Method import java.util.Calendar;
public class CalendarClassDemo {
public static void main(String args[])
{
// Creating a calendar object
Calendar calndr = Calendar.getInstance();
// Displaying the Current Date
System.out.println( "Current Date&Time: "
+ calndr.getTime());
// Clear method for undefining the values
// of the calendar
calndr.clear();
// Displaying the final result
System.out.println( "After clear method: "
+ calndr.getTime());
}
} |
Output:
Current Date&Time: Tue Feb 12 13:01:42 UTC 2019 After clear method: Thu Jan 01 00:00:00 UTC 1970
Example 2:
// Java Code to illustrate clone() Method import java.util.*;
public class CalendarClassDemo {
public static void main(String args[])
{
// Creating a calendar object
Calendar calndr1 = new GregorianCalendar( 2018 , 12 , 2 );
// Displaying current calendar
System.out.println( "Original calendar: "
+ calndr1.getTime());
// Clear method for undefining the values
// of the calendar
calndr1.clear();
// Displaying the final result
System.out.println( "After clear method: "
+ calndr1.getTime());
}
} |
Output:
Original calendar: Wed Jan 02 00:00:00 UTC 2019 After clear method: Thu Jan 01 00:00:00 UTC 1970
