java.time包中的Duration Class的toMillis()方法用於獲取此持續時間的值(以毫秒為單位)。
用法:
public long toMillis()
參數:此方法不接受任何參數。
返回值: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.toMillis()方法:
示例1:
// Java code to illustrate toMillis() 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 toMillis() method
System.out.println(duration.toMillis());
}
}
輸出:
Duration: PT51H4M 183840000
示例2:
// Java code to illustrate toMillis() 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 toMillis() method
System.out.println(duration.toMillis());
}
}
輸出:
Duration: PT0.01S 10
