java.time包中的Duration Class的toNanosPart()方法用于在持续时间的秒数内获取纳秒部分。
用法:
public long toNanosPart()
参数:此方法不接受任何参数。
返回值:此方法返回一个long值,该值是持续时间(秒)内的纳秒部分。
以下示例说明了Duration.toNanosPart()方法:
示例1:
// Java code to illustrate toNanosPart() method
import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Duration using parse() method
Duration duration
= Duration.parse("P2DT3H4M");
System.out.println("Duration: "
+ duration);
// Get the number of nano-seconds
// using toNanosPart() method
System.out.println(duration.toNanosPart());
}
}
输出:
Duration: PT51H4M 0
示例2:
// Java code to illustrate toNanosPart() method
import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Duration using ofNanos() method
Duration duration = Duration.ofNanos(10);
System.out.println("Duration: "
+ duration);
// Get the number of nano-seconds
// using toNanosPart() method
System.out.println(duration.toNanosPart());
}
}
输出:
Duration: PT0.00000001S 10
