Java .isLenient()

The .isLenient() method of the Calendar class returns True if the interpretation of this Calendar is lenient else it returns False.

Syntax

calendar.isLenient()

Note: When a Calendar is lenient, it allows date and time values that may not make sense in a real-world context. For example, February 30th or a time value of 25:70:90 would be accepted. When a Calendar is non-lenient, it enforces stricter rules, and attempting to set invalid date or time values will throw exceptions, such as IllegalArgumentException.

Example 1

The example below demonstrates the use of the .isLenient() method.

import java.util.Calendar;
public class CalendarIsLenientExample {
  public static void main(String args[]){

    // Creating a calendar object
    Calendar cal = Calendar.getInstance();

    // Displaying the calendar
    System.out.println("Current Calendar: " + cal.getTime());

    // Checking the leniency
    boolean leniency = cal.isLenient();

    // Displaying the leniency
    System.out.println("Calendar is" + " lenient: " + leniency);
  }
}
