Java Batch File???

Don't know if that is the right term for it.

I want my java console app to do something every five seconds until I tell it to stop. i.e. poll a mobile over serial port for new messages.

It's been years since I even wrote a non GUI java app.

Would this be achieved through case statements or what?

threads using sleep , sounds like the easiest to me.

lookup the api's

yeah have your polling section in a seperate thread, then use thread.sleep(miliseconds)

A better solution, if you have some of your own java code on the mobile is to fire an event which the client java app listens for. This way you are not continuously polling and only act when the event you are interested actually happens

NotMe

try {
   Thread.sleep(300000);
}
catch(InterruptedException ex) {
   ex.printStackTrace();
}

Wait for 300000 seconds = 5 minutes. Just put that in a loop with whatever else you want to do.

What I meant was more how to stop it looping?

[When I want it to stop of course, i.e. stop it in a controlled manner, would this be a case statement?]

MrPinK

public class Foo extends Thread
{
    private boolean stopped;

    public void run()
    {
        stopped = false;
        while(!stopped)
        {
            // poll your phone here
            Thread.sleep(300000);
        }
    }

    // can't call the method stop() cause that's a depreciated thread method
    public void end()  
    {
        stopped = true;
    }
}

That's the standard way for stopping a thread. Since they depreciated the stop method. The thread loops based on a boolean variable which can be changed by other threads. From your main class you start the thread, and wait for some user input like a certain key press. Then you call the end method.

Thanks,

I'll give that a go this afternoon.
