Java Duration toNanosPart()方法及实例
java.time包中Duration类的toNanosPart()方法用于获取持续时间的秒内的纳秒部分。
语法。
public long toNanosPart()
参数。此方法不接受任何参数。
返回值。该方法返回一个长值,即持续时间中秒级的纳秒部分。
下面的例子说明了Duration.toNanosPart()方法。
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
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
