参数:该方法不接受任何参数作为参数。

返回值:该方法返回一年中由特定日本日期表示的整数形式的天数。

下面举例说明 lengthOfYear() 方法:

例 1:

Java 语言(一种计算机语言，尤用于创建网站)

// Java program to demonstrate
// lengthOfYear() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // Creating and initializing
            // japaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.of(2006, 06, 23);

            // Getting length of a year
            // by using lengthOfYear() method
            int length = hidate.lengthOfYear();

            // Display the result
            System.out.println("no of day present: "
                               + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

no of day present: 365

例 2:

Java 语言(一种计算机语言，尤用于创建网站)

// Java program to demonstrate
// lengthOfYear() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // Creating and initializing
            // japaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();

            // Getting length of a year
            // by using lengthOfYear() method
            int length = hidate.lengthOfYear();

            // Display the result
            System.out.println("no of day present: "
                               + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

no of day present: 366
