Java OffsetTime plusSecond()用法及代碼示例

OffsetTime類的plusSeconds()方法用於將指定的秒數值添加到此OffsetTime並將結果作為OffsetTime對象返回。這一瞬間是一成不變的。計算大約在午夜結束。

用法:

public OffsetTime plusSeconds(long SecondsToAdd)

參數：此方法接受單個參數SecondsToAdd，該參數是要添加的Seconds的值，它可以是負值。

返回值：此方法基於此時間返回OffsetTime並添加了Seconds。

以下示例程序旨在說明plusSeconds()方法：

示例1:

// Java program to demonstrate 
// OffsetTime.plusSeconds() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a OffsetTime object 
        OffsetTime time 
            = OffsetTime.parse("21:15:10+11:10"); 
  
        // print OffsetTime 
        System.out.println("OffsetTime before addition: "
                           + time); 
  
        // add 200 Seconds using plusSeconds() 
        OffsetTime value = time.plusSeconds(200); 
  
        // print result 
        System.out.println("OffsetTime after addition: "
                           + value); 
    } 
}

輸出：

OffsetTime before addition: 21:15:10+11:10
OffsetTime after addition: 21:18:30+11:10

示例2:

// Java program to demonstrate 
// OffsetTime.plusSeconds() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a OffsetTime object 
        OffsetTime time 
            = OffsetTime.parse("14:25:10+01:10"); 
  
        // print OffsetTime 
        System.out.println("OffsetTime before addition: "
                           + time); 
  
        // add -3400 Seconds using plusSeconds() 
        OffsetTime value = time.plusSeconds(-3400); 
  
        // print result 
        System.out.println("OffsetTime after addition: "
                           + value); 
    } 
}

輸出：

OffsetTime before addition: 14:25:10+01:10
OffsetTime after addition: 13:28:30+01:10
