Java中的 LocalTime toNanoOfDay() 方法及示例

LocalTimetoNanoOfDay()方法用于从该 LocalTime 返回时间的纳秒。此方法返回的值介于 0 到 24 * 60 * 60 * 1、000、000、000 – 1 之间。

句法:

public long toNanoOfDay()

参数:此方法不接受任何参数。

返回值:该方法返回一个long值,它是天的nano值,相当于这个时间。

下面的程序说明了 toNanoOfDay() 方法:

方案一:

// Java program to demonstrate
// LocalTime.toNanoOfDay() 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");
  
        // extract nano of day from toNanoOfDay()
        long value = time.toNanoOfDay();
  
        // print result
        System.out.println("Nano of day: "
                           + value);
    }
}
输出:
Nano of day: 70490630000000

方案二:

// Java program to demonstrate
// LocalTime.toNanoOfDay() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("23:21:45.98");
  
        // extract nano of day from toNanoOfDay()
        long value = time.toNanoOfDay();
  
        // print result
        System.out.println("Nano of day: "
                           + value);
    }
}
输出:
Nano of day: 84105980000000
