Java 中的等时日期(临时处理器)方法，示例
原文:https://www . geesforgeks . org/isochronomics-datetime alaccessor-method-in-Java-with-example/
Java . time . chrono . isochronology类的 date() 方法用于根据 ISO 系统从另一个临时处理器对象获取本地日期。
语法:
public LocalDate date(TemporalAccessor temporal)
参数:该方法以任意时态取值器的对象为参数。
返回值:该方法从另一个 TemporalAccessor 对象返回根据 Iso 日历系统的本地日期。
以下是说明日期()方法的示例:
例 1:
// Java program to demonstrate
// date() 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();
// creating and initializing
// TemporalAccessor object
ZonedDateTime zonedate
= ZonedDateTime.parse(
"2018-10-25T23:12:31."
+ "123+02:00[Europe/Paris]");
// getting HijrahDate for the
// given TemporalAccessor object
// by using date() method
LocalDate date = crono.date(zonedate);
// 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);
}
}
}
输出:
LocalDate is: 2018-10-25
例 2:
// Java program to demonstrate
// date() 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();
// creating and initializing TemporalAccessor object
LocalDateTime localdate
= LocalDateTime
.parse("2018-12-30T19:34:50.63");
// getting HijrahDate for the
// given TemporalAccessor object
// by using date() method
LocalDate date = crono.date(localdate);
// 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);
}
}
}
输出:
LocalDate is: 2018-12-30
