Java 中的年月长()方法，示例

原文:https://www . geesforgeks . org/year month-length of year-in-method-in-Java-with-examples/

Java 中 YearMonth 类的 lengthOfYear() 方法用来返回这个 year-month 对象值的年长度，以天数表示。根据年份是否为闰年，一年的长度值可以是 365 或 366。

语法:

public int lengthOfYear()

参数:该方法不接受任何参数。

返回值:返回一个以天数表示年长的整数值。

以下程序说明了 Java 中 YearMonth 的 lengthOfYear()方法: 程序 1 :

// Program to illustrate the lengthOfYear() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        // Create YearMonth object
        YearMonth yearMonth = YearMonth.of(2016, 2);

        // Print the length of year in Number
        // of days, 366 in this case as 2016 is
        // a Leap Year
        System.out.println(yearMonth.lengthOfYear());
    }
}

Output:

366

程序 2 :

// Program to illustrate the lengthOfYear() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        // Create YearMonth object
        YearMonth yearMonth = YearMonth.of(1990, 2);

        // Print the length of year in Number
        // of days, 365 in this case as 1990 is
        // not a Leap Year
        System.out.println(yearMonth.lengthOfYear());
    }
}

Output:

365
