Java程序获取两个时刻之间的持续时间
创建两个时刻：
Instant time1 = Instant.now(); Instant time2 = Instant.now().plusSeconds(50);
使用between()得到两个时刻之间的时间：
long resMilli = Duration.between(time1, time2).toMillis();
示例
import java.time.Duration;
import java.time.Instant;
public class Demo {
public static void main(String[] args) {
Instant time1 = Instant.now();
Instant time2 = Instant.now().plusSeconds(50);
long resMilli = Duration.between(time1, time2).toMillis();
System.out.println("Duration between two time intervals = "+resMilli);
}
}输出结果
Duration between two time intervals = 50000
