Get JVM up time

This is an example of how to get the JVM up time. We are using the We are using the RuntimeMXBean, that is the management interface for the runtime system of the Java virtual machine. Getting the JVM up time implies that you should:

  • Get the JVM’s thread system bean, that is the RuntimeMXBean, using the getRuntimeMXBean() API method of ManagementFactory.
  • Use getUptime() API method of RutimeMXBean. This method returns the uptime of the Java virtual machine in milliseconds.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;
public class GetJVMUpTime {
	public static void main(String[] args) {

     	RuntimeMXBean bean = ManagementFactory.getRuntimeMXBean();
  // Get JVM up time and print it

  double upTime = bean.getUptime();

  System.out.println("JVM up time = " + upTime + " ms");


JVM up time = 23.0 ms

This was an example of how to get the JVM up time in Java.
