Java LocalTime plusNanos()用法及代码示例


LocalTime类的plusNanos()方法用于向此LocalTime添加指定的毫微秒值,并将结果作为LocalTime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 LocalTime 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LocalTime,并添加了纳秒。

以下示例程序旨在说明plusNanos()方法:

示例1:

// Java program to demonstrate 
// LocalTime.plusNanos() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a LocalTime object 
        LocalTime time 
            = LocalTime.parse("19:34:50.63"); 
  
        // print LocalTime 
        System.out.println("LocalTime before add: "
                           + time); 
  
        // add 34000000 nanoseconds using plusNanos() 
        LocalTime value = time.plusNanos(34000000); 
  
        // print result 
        System.out.println("LocalTime after add: "
                           + value); 
    } 
}
输出:
LocalTime before add: 19:34:50.630
LocalTime after add: 19:34:50.664

示例2:

// Java program to demonstrate 
// LocalTime.plusNanos() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a LocalTime object 
        LocalTime time 
            = LocalTime.parse("01:00:01"); 
  
        // print LocalTime 
        System.out.println("LocalTime before add: "
                           + time); 
  
        // add -971200000 nanoseconds  using plusNanos() 
        LocalTime value = time.plusNanos(-971200000); 
  
        // print result 
        System.out.println("LocalTime after add: "
                           + value); 
    } 
}
输出:
LocalTime before add: 01:00:01
LocalTime after add: 01:00:00.028800
