Java中的持续时间 toSeconds() 方法及示例
使用Java.time 包中Duration 类的toSeconds()方法获取此持续时间的秒数值。
句法:
public long toSeconds()
参数:此方法不接受任何参数。
返回值:此方法返回一个长值,即此持续时间的秒数。
下面的示例说明了 Duration.toSeconds() 方法:
示例 1:
// Java code to illustrate toSeconds() 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 seconds
// using toSeconds() method
System.out.println(duration.toSeconds());
}
}
输出:
Duration: PT51H4M
183840
示例 2:
// Java code to illustrate toSeconds() method
import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Duration using ofSeconds() method
Duration duration
= Duration.ofSeconds(10);
System.out.println("Duration: "
+ duration);
// Get the number of seconds
// using toSeconds() method
System.out.println(duration.toSeconds());
}
}
输出:
Duration: PT10S
10
