The following code snippet demonstrates how to get the time for how long has the JVM been running.
package org.kodejava.lang.management;
import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
public class GetUptime {
public static void main(String[] args) {
RuntimeMXBean bean = ManagementFactory.getRuntimeMXBean();
// Returns the uptime of the Java virtual machine in
// milliseconds.
long uptime = bean.getUptime();
System.out.printf("Uptime = %d (ms).", uptime);
}
}
The output of the code snippet above:
Uptime = 125 (ms).
