How can port AsyncTask from Android to java?

Question

AsyncTask is very useful to synchronized between UI thread and other threads in Android. So I have read its source code and tried porting to java classic (JDK) but no success because some classes don't exist in java (Message, Handler..).
I would like to create a class with some useful functions like AsyncTask (that can synchronized between main thread and other threads) :

    doInBackground(Params... params)
    onProgressUpdate(Progress... values)
    onPostExecute(Result result)
    publishProgress(Progress... values)
    onPreExecute()
    onCancelled()

Is there any way to try that?

Agreed that SwingWorker is the most direct analog to AsyncTask

If you aren't using Swing, another option is a ThreadPoolExecutor: http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ThreadPoolExecutor.html

Here's an article demonstrating using ThreadPoolExecutor to spawn multiple background threads: http://www.javacodegeeks.com/2013/01/java-thread-pool-example-using-executors-and-threadpoolexecutor.html

Spawning a single background thread that runs and completes without progress update (which is also a common use of AsyncTask in Android) can be as simple as:

Executors.newSingleThreadExecutor().execute(new Runnable() {
  @Override
  public void run() {
    // do stuff in background
  }
});

1. AsyncTask is specially developed for android to sync the UI thread and the Non-UI thread, also known as Painless threading.....

2. There is an alternative of AsyncTask in Java named as SwingWorker.

See this link for a nice basic tutorial:
