Best way to let a scheduler run in a new thread

Plugins Plugin Development

Hey,
as I know, it’s better, when I create a new thread for “heavy” calculations in combination with database connections.
The scheduler is placed in a new class, which gets called / created on GameStartedServerEvent with new TaxScheduler(this, logger);

Scheduler class:

public TaxScheduler(Main plugin, Logger logger) throws IOException {
	Scheduler scheduler = Sponge.getGame().getScheduler();
	Task.Builder taskBuilder = scheduler.createTaskBuilder();

	taskBuilder.execute(new Runnable() {
		public void run() {
                //code
		}

	}).interval(60, TimeUnit.SECONDS).name("Tax Updater").submit(plugin);
}

My code works, but I want to open it in a new thread. I did this before, but I’m new to java and don’t know the best way to do this.

Is there a better way, or is it “ok”, when I do it like this:

new Thread()
        {
            public void run() {
                try {
                    new TaxScheduler(plugin, logger);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }.start();

Greets :slight_smile:

Use the first method, but call the async() method on the builder.

So this method will run my scheduler in a new thread?
(Right?) Example:
Task.Builder taskBuilder = scheduler.createTaskBuilder().async();

Exactly. Calling async().submit(...) on a TaskBuilder executes the task in a new (or pooled) thread. That’s in most cases faster than creating your own thread. But keep in mind that most parts of the Sponge API are not thread safe!

It may be useful to read the javadoc for async() so that you understand what it actually means.
