For multithreading, I discovered about a year ago the Executors,
ExecutorService, Future, and Callable classes that make multithreading
dead-easy.

For example:

ExecutorService exec =
Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors());

class DoSomething implements Callable<ImagePlus> {
    public ImagePlus call() {
        // generate an image
        ImagePlus imp = new ImagePlus("that", new FloatProcessor(500, 500));
        return imp;
    }
}


Future<ImagePlus> fu = exec.submit(new DoSomething());

// blocks until it's done:
ImagePlus result = fu.get();

result.show();


// when done:
exec.shutdown();

It's very convenient to operate over very large collections of objects
or operations.
