原文:https://www . geesforgeks . org/isochronomics-datyealdayint-int-method-in-Java-with-example/
Java . time . chrono . isochronology类的 dateYearDay() 方法用于根据特定年份和日期的 Iso 日历检索本地日期。
语法:
public LocalDate dateYearDay(int prolepticYear,
int dayOfYear)
参数:该方法以下列参数为参数:
- 年:是 LocalDate 年字段的整数优先年
- 日:是 LocalDate 的日字段的整数日
返回值:该方法根据特定年份和日期的 Iso 日历返回当地日期。
以下是举例说明 dateYearDay() 方法的例子:
例 1:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to demonstrate
// dateYearDay() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing LocalDate Object
LocalDate hidate = LocalDate.now();
// getting IsoChronology used in LocalDate
IsoChronology crono = hidate.getChronology();
// getting LocalDate for the
// given date and year field
// by using dateYearDay() method
LocalDate date = crono.dateYearDay(1440, 24);
// display the result
System.out.println("LocalDate is: " + date);
}
catch (DateTimeException e) {
System.out.println("passed parameter can "
+ "not form a date");
System.out.println("Exception thrown: " + e);
}
}
}
Output:
LocalDate is: 1440-01-24
例 2:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to demonstrate
// dateYearDay() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing LocalDate Object
LocalDate hidate = LocalDate.now();
// getting IsoChronology used in LocalDate
IsoChronology crono = hidate.getChronology();
// getting LocalDate for the
// given date and year field
// by using dateYearDay() method
LocalDate date = crono.dateYearDay(999999999, 32);
// display the result
System.out.println("LocalDate is: " + date);
}
catch (DateTimeException e) {
System.out.println("passed parameter can "
+ "not form a date");
System.out.println("Exception thrown: " + e);
}
}
}
Output:
LocalDate is: +999999999-02-01
