Java中的 JapaneseDate lengthOfYear() 方法及示例

Java.time.chrono.JapaneseDate类的lengthOfYear()方法用于获取由特定日本日期表示的一年中存在的天数。

句法:

public int lengthOfYear()

参数:此方法不接受任何参数作为参数。

返回值:此方法返回由特定日本日期表示的一年中以整数值形式存在的天数

以下是说明lengthOfYear()方法的示例:

示例 1:

Java
// 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);
        }
    }
}


Java
// 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);
        }
    }
}


输出:
no of day present: 365

                = 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);
        }
    }
}
输出:
no of day present: 366
