Java OffsetTime plusNanos()用法及代码示例

OffsetTime类的plusNanos()方法用于向此OffsetTime添加指定的毫微秒值，并将结果作为OffsetTime对象返回。这一瞬间是一成不变的。计算大约在午夜结束。

用法:

public OffsetTime plusNanos(long nanosecondsToAdd)

参数：此方法接受单个参数nanosecondsToAdd，该参数是要添加的纳秒值，它可以是负值。

返回值：此方法基于此时间返回OffsetTime(添加了纳秒)。

以下示例程序旨在说明plusNanos()方法：

示例1:

// Java program to demonstrate 
// OffsetTime.plusNanos() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a OffsetTime object 
        OffsetTime time 
            = OffsetTime.parse("12:25:10+01:00"); 
  
        // print OffsetTime 
        System.out.println("OffsetTime before add: "
                           + time); 
  
        // add 34000000 nanoseconds using plusNanos() 
        OffsetTime value = time.plusNanos(34000000); 
  
        // print result 
        System.out.println("OffsetTime after add: "
                           + value); 
    } 
}

输出：

OffsetTime before add: 12:25:10+01:00
OffsetTime after add: 12:25:10.034+01:00

示例2:

// Java program to demonstrate 
// OffsetTime.plusNanos() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a OffsetTime object 
        OffsetTime time 
            = OffsetTime.parse("12:25:10+01:00"); 
  
        // print OffsetTime 
        System.out.println("OffsetTime before add: "
                           + time); 
  
        // add -971200000 nanoseconds  using plusNanos() 
        OffsetTime value = time.plusNanos(-971200000); 
  
        // print result 
        System.out.println("OffsetTime after add: "
                           + value); 
    } 
}

输出：

OffsetTime before add: 12:25:10+01:00
OffsetTime after add: 12:25:09.028800+01:00
