Calendar setLenient() Method in Java with Examples

The setLenient(boolean leniency) method in Calendar class is used to specify whether the interpretation of the date and time is to be lenient or not.

Syntax:

public void setLenient(boolean leniency)

Return Value: The method does not return any value.

Below programs illustrate the working of setFirstDayOfWeek() Method of Calendar class:
Example 1:

// Java code to illustrate
// setLenient() method

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

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

        // Displaying the current
        // mood of leniency
        boolean value = calndr.isLenient();
        System.out.println("Is the"
                           + " Calendar lenient? "
                           + value);

        // Changing the leniency
        calndr.setLenient(false);

        // Displaying the result
        System.out.println("The altered"
                           + " Leniency: "
                           + calndr.isLenient());
    }
}

Output:

Is the Calendar lenient? true
The altered Leniency: false

Example 2:

// Java code to illustrate
// isLenient() method

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

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

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

        // Checking the leniency
        boolean leniency = calndr.isLenient();
        calndr.setLenient(false);
        leniency = calndr.isLenient();

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

        // Checking the leniency
        calndr.setLenient(true);
        leniency = calndr.isLenient();

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

Output:

Current Calendar: Thu Feb 21 11:00:50 UTC 2019
Calendar is lenient? false
Calendar is lenient: true
