Java 中的等时 localDateTime()方法，示例
原文:https://www . geesforgeks . org/isochronomics-local datetime-method-in-Java-with-example/
Java . time . chrono . isochronology类的 localDateTime() 方法用于根据 Iso 日历系统从时态访问器的任何其他对象中检索本地日期和时间。
语法:
public LocalDateTime localDateTime(
TemporalAccessor temporal)
参数:该方法以任意时态取值器的对象为参数。
返回值:该方法根据 Iso 日历系统从时态访问器的任何其他对象返回本地日期和时间。
以下是说明 localDateTime() 方法的示例:
例 1:
// Java program to demonstrate
// localDateTime() 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 LocalDate for the
// given TemporalAccessor object
// by using localDateTime() method
LocalDateTime date
= crono.localDateTime(zonedate);
// display the result
System.out.println("LocalDateTime is: "
+ date);
}
catch (DateTimeException e) {
System.out.println("passed parameter can"
+ " not form a date");
System.out.println("Exception thrown: " + e);
}
}
}
输出:
LocalDateTime is: 2018-10-25T23:12:31.123
例 2:
// Java program to demonstrate
// localDateTime() 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 LocalDate for the
// given TemporalAccessor object
// by using localDateTime() method
LocalDateTime date
= crono.localDateTime(localdate);
// display the result
System.out.println("LocalDateTime is: "
+ date);
}
catch (DateTimeException e) {
System.out.println("passed parameter can"
+ " not form a date");
System.out.println("Exception thrown: " + e);
}
}
}
输出:
LocalDateTime is: 2018-12-30T19:34:50.630
