从Java中的RuntimeMXBean获得JVM正常运行时间
Java虚拟机的运行时系统管理界面中的RuntimeMXBean-
RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();
让我们使用getUptime()方法获得JVM正常运行时间-
runtimeMX.getUptime()
以下是一个例子-
示例
import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
import java.util.Date;
public class Demo {
public static void main(String args[]) throws Exception {
RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();
System.out.println("JVM Uptime = "+runtimeMX.getUptime() + " ms");
}
}输出结果
JVM Uptime = 81 ms
让我们再次运行代码，以获取以下输出-
JVM Uptime = 78 ms
