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
