The clear(int cal_field) method in Calendar class is used to set a given calendar field value and the time value of this Calendar undefined.
Note: Implementation of calendar class may use default field values for date and time calculations.

Parameters: The method takes one parameter cal_field of Integer type and refers to the field value that is to be made undefined.
Return Value: The method does not return any value.
Below programs illustrate the working of clear() Method of Calendar class:
Example 1:
// 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 month // of the calendar calndr.clear(Calendar.MONTH); // Displaying the final result System.out.println("After clear method: " + calndr.getTime()); }} |
Output:
Current Date&Time: Wed Mar 27 09:03:26 UTC 2019 After clear method: Sun Jan 27 09:03:26 UTC 2019
Example 2:
// 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 year // of the calendar calndr.clear(Calendar.YEAR); // Displaying the final result System.out.println("After clear method: " + calndr.getTime()); }} |
Output:
Current Date&Time: Wed Mar 27 09:03:32 UTC 2019 After clear method: Fri Mar 27 09:03:32 UTC 1970
