How to Poweroff a Virtual Machine using Oracle VirtualBox Java API?

Question

I'm learnig to use VirtualBox Java API, but the documentation is not good.

My code:

VirtualBoxManager virtualBoxManager = VirtualBoxManager.createInstance(null);

IVirtualBox vbox = virtualBoxManager.getVBox();
List<IMachine> machines= vbox.getMachines();

for (IMachine m : machines) {
    System.out.println("Name: " + m.getName() + " OS: " + m.getOSTypeId());
    virtualBoxManager.startVm(m.getName(), null, 7000); //Starting a VM
}

virtualBoxManager.cleanup();

How I stop a VM?

import org.virtualbox_5_0.*;

public class VirtualboxVMStop {

    public static void main(String[] args) {

        String machineName = "Centos_1";
        String url = "http://localhost:18083";
        String user = "test";
        String passwd = "test";

        VirtualBoxManager mgr = VirtualBoxManager.createInstance(null);
        mgr.connect(url, user, passwd);

        // Get the virtual machine you need to connect to.
        IVirtualBox vbox = mgr.getVBox();
        IMachine machine = vbox.findMachine(machineName);

        ISession session = null;
        IProgress prog;

        // Determine the status of the virtual machine.
        MachineState state = machine.getState();
        System.out.println(state);

        if (MachineState.Running == state) {
            session = mgr.getSessionObject();
            machine.lockMachine(session, LockType.Shared);
            prog = session.getConsole().powerDown();
            prog.waitForCompletion(10000);
            session.unlockMachine();
        } else {
            System.out.println(machineName+" is PoweredOff!");
        }
    }
}
