Java中的 Calendar isLenient() 方法及示例

Calendar 类中的isLenient()方法用于了解和理解该 Calendar 的日期和时间解释是否被认为是宽松的。
句法：

public boolean isLenient()

参数：该方法不带任何参数。
返回值：如果此 Calendar 的解释是宽松的，则该方法要么返回True ，否则返回False 。
下面的程序说明了 Calendar 类的 isLenient() 方法的工作原理：
示例 1：

Java

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

输出

Current Calendar: Tue Nov 30 10:25:50 UTC 2021
Calendar is lenient: true

示例 2：

Java

// 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);
    }
}

输出

Current Calendar: Tue Nov 30 10:26:18 UTC 2021
Calendar is lenient: false
