Java 中的即时调整()方法，示例
原文:https://www . geesforgeks . org/instant-adjustin to-method-in-Java-with-example/
即时类的调整(时态时态)方法调整传递的时态对象，使其具有应用该方法的瞬间。
语法:
public Temporal adjustInto(Temporal temporal)
参数:该方法接受一个参数时间，该参数是要调整的目标时间对象。它不应为空。
返回值:该方法返回调整后的时态对象。
异常:此方法抛出以下异常:
- datetimeexception If this method cannot be adjusted.
- Arithmetic exception If there is a numerical overflow during adjustment.
下面的程序说明了 Instant.adjustInto()方法:
程序 1:
// Java program to demonstrate
// Instant.adjustInto() method
import java.time.*;
import java.time.temporal.Temporal;
public class GFG {
public static void main(String[] args)
{
// create an instance object
Instant instant
= Instant.parse("2018-11-20T16:55:30.00Z");
// create a Temporal object
// which is equal to OffsetDateTime object
OffsetDateTime passTemporal
= OffsetDateTime.now();
// print passed Value
System.out.println("Passed Value: "
+ passTemporal);
// apply adjustInto method
// to adjust OffsetDateTime Temporal
// to instant object
Temporal returnTemporal
= instant.adjustInto(passTemporal);
// print results
System.out.println("Returned Value: "
+ (OffsetDateTime)returnTemporal);
}
}
输出:
Passed Value: 2018-11-22T09:22:17.297Z
Returned Value: 2018-11-20T16:55:30Z
程序二:
// Java program to demonstrate
// Instant.adjustInto() method
import java.time.*;
import java.time.temporal.Temporal;
public class GFG {
public static void main(String[] args)
{
// create an instance object
Instant instant
= Instant.parse("2018-11-17T06:50:39.00Z");
// create a Temporal object
// which is equal to ZonedDateTime object
ZonedDateTime passTemporal
= ZonedDateTime.now();
// print passed Value
System.out.println("Passed Value: "
+ passTemporal);
// apply adjustInto method
// to adjust ZonedDateTime Temporal
// to instant object
Temporal returnTemporal
= instant.adjustInto(passTemporal);
// print results
System.out.println("Returned Value: "
+ (ZonedDateTime)returnTemporal);
}
}
输出:
Passed Value: 2018-11-22T09:22:20.995Z[Etc/UTC]
Returned Value: 2018-11-17T06:50:39Z[Etc/UTC]
程序 3:
// Java program to demonstrate
// Instant.adjustInto() method
import java.time.*;
import java.time.temporal.Temporal;
public class GFG {
public static void main(String[] args)
{
// create an instance object
Instant instant
= Instant.parse("2017-11-01T16:25:00.00Z");
// create a Temporal object
// which is equal to Instant object
// with current Instant
Temporal passTemporal
= Instant.now();
// print passed Value
System.out.println("Passed Value: "
+ passTemporal);
// apply adjustInto method to adjust Temporal
// to this instant object
Temporal returnTemporal
= instant.adjustInto(passTemporal);
// print results
System.out.println("Returned Value: "
+ returnTemporal);
}
}
输出:
Passed Value: 2018-11-22T09:22:23.298Z
Returned Value: 2017-11-01T16:25:00Z
