Java OffsetTime from()用法及代碼示例

Java中的OffsetTime類的from()方法從時態對象獲取OffsetTime的實例，該對象在方法的參數中傳遞。

用法:

public static OffsetTime from(TemporalAccessor temporal)

參數：此方法接受單個強製性參數temporal，該參數指定要轉換的時間對象，並且不為null。

返回值：它返回偏移時間，而不是null。

以下示例程序旨在說明from()方法：

示例1:

// Java program to demonstrate the from() method 
  
import java.time.OffsetTime; 
import java.time.ZonedDateTime; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // Function called to get current time 
        OffsetTime time 
            = OffsetTime.from(ZonedDateTime.now()); 
  
        // Prints the current time 
        System.out.println("Current-time: "
                           + time); 
    } 
}

輸出：

Current-time: 13:07:59.941Z

程序2：

// Java program to demonstrate the from() method 
  
import java.time.OffsetTime; 
import java.time.ZonedDateTime; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // Function called to get current time 
        OffsetTime time 
            = OffsetTime.from(ZonedDateTime.now()); 
  
        // Prints the current time 
        System.out.println("Current-time: "
                           + time); 
    } 
}

輸出：

Current-time: 13:08:03.087Z
