Java程序可从几秒钟创建持续时间
我们将根据天，小时，毫秒和分钟在这里获得秒数，例如，十天内的秒数，十小时的秒数等。
持续时间（天，小时，毫秒和分钟）：
Duration duration = Duration.ofDays(10); Duration duration1 = Duration.ofHours(10); Duration duration2 = Duration.ofMillis(10); Duration duration3 = Duration.ofMinutes(10);
现在，获取秒：
System.out.println("Seconds in 10 days = "+duration.getSeconds());
System.out.println("Seconds in 10 hours = "+duration1.getSeconds());
System.out.println("Seconds in 10 milliseconds = "+duration2.getSeconds());
System.out.println("Seconds in 10 minutes = "+duration3.getSeconds());示例
import java.time.Duration;
public class Demo {
public static void main(String[] args) {
Duration duration = Duration.ofDays(10);
Duration duration1 = Duration.ofHours(10);
Duration duration2 = Duration.ofMillis(10);
Duration duration3 = Duration.ofMinutes(10);
System.out.println("Seconds in 10 days = "+duration.getSeconds());
System.out.println("Seconds in 10 hours = "+duration1.getSeconds());
System.out.println("Seconds in 10 milliseconds = "+duration2.getSeconds());
System.out.println("Seconds in 10 minutes = "+duration3.getSeconds());
}
}输出结果
Seconds in 10 days = 864000 Seconds in 10 hours = 36000 Seconds in 10 milliseconds = 0 Seconds in 10 minutes = 600
