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()); } } |
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()); } } |
