Java中的 OffsetTime adjustInto() 方法及示例

Java中 OffsetDateTime 类的adjustInto()方法将指定的时间对象调整为与该对象具有相同的时间。

句法 :

public Temporal adjustInto(Temporal temporal)

参数:此方法接受单个参数temporal ,它指定要调整的目标对象,而不是 null。

返回值:返回调整后的对象,不为空

错误和异常:此方法抛出两个异常,如下所述:

  • DateTimeException : 如果无法进行调整。
  • ArithmeticException : 如果发生数值溢出。

下面的程序说明了 adjustInto() 方法:

程序 1:

// Java program to demonstrate the adjustInto() method
  
import java.time.OffsetTime;
import java.time.ZonedDateTime;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Current time
        ZonedDateTime date = ZonedDateTime.now();
  
        // Prints the current time
        System.out.println("Current date:" + date);
  
        // Parsed the date
        OffsetTime date1 = OffsetTime.parse("14:30:30+05:00");
  
        // Adjusts
        date = (ZonedDateTime)date1.adjustInto(date);
        System.out.println("Adjusted date:" + date);
    }
}
输出:
Current date:2018-12-11T10:01:37.877Z[Etc/UTC]
Adjusted date:2018-12-11T14:30:30Z[Etc/UTC]

方案二

// Java program to demonstrate the adjustInto()
// method exceptions
  
import java.time.OffsetTime;
import java.time.ZonedDateTime;
  
public class GFG {
    public static void main(String[] args)
    {
        try {
            // Current time
            // Current time
            ZonedDateTime date = ZonedDateTime.now();
  
            // Prints the current time
            System.out.println("Current date:" + date);
  
            // Parsed the date
            OffsetTime date1 = OffsetTime.parse("25:30:30+05:00");
  
            // Adjusts
            date = (ZonedDateTime)date1.adjustInto(date);
            System.out.println("Adjusted date:" + date);
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
输出:
Current date:2018-12-11T10:01:42.520Z[Etc/UTC]
java.time.format.DateTimeParseException: Text '25:30:30+05:00' could not be parsed: Invalid value for HourOfDay (valid values 0 - 23): 25
