通過使用java.time包中的Duration Class的toMillisPart()方法,將納秒數除以1,000,000,以毫秒為單位獲取此持續時間的值。
用法:
public long toMillisPart()
參數:此方法不接受任何參數。
返回值:通過將納秒數除以1,000,000,此方法返回一個long值,該值是此持續時間中的毫秒數。
以下示例說明了Duration.toMillisPart()方法:
示例1:
// Java code to illustrate toMillisPart() 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 milli-seconds
// using toMillisPart() method
System.out.println(duration.toMillisPart());
}
}
輸出:
Duration: PT51H4M 0
示例2:
// Java code to illustrate toMillisPart() method
import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Duration using ofMillis() method
Duration duration = Duration.ofMillis(10);
System.out.println("Duration: "
+ duration);
// Get the number of milli-seconds
// using toMillisPart() method
System.out.println(duration.toMillisPart());
}
}
輸出:
Duration: PT0.01S 10
