SwingWorker class, the process method

[Dirk94]

I'm currently experimenting with the SwingWorker class.
I've created a Swingworker Class:

class DownloadWorker extends SwingWorker<Integer, Integer> {

In this class I've overriden the following methods:

@Override
protected Integer doInBackground() throws Exception {

and

@Override
  protected void done() {

However my problem came with the publish and process methods.
I've looked into many online articles but I just cannot fully understand these two methods and ther cooperation.
I've added the following code (just for the sake of the example) in the doInBackground method:

@Override
protected Integer doInBackground() throws Exception {
  for (int i=0; i<10000; i++) {
    publish(i);
  }
}

When I add the following in the downloadWorker class:

protected void process( int a) {
    System.out.println("process method!: a = " + a);
  }

There are no errors but the process method is never executed.
So I went looking further for a solution and came up with the following:

 protected void process( java.util.List<Object> chunks) {
 
  }

I work in netbeans 7.0.1 and netbeans gives me the following error: "name clash: process(java.util.List<java.lang.Object>) in download.DownloadWorker and process(java.util.List<V>) in javax.swing.SwingWorker have the same erasure, yet neither overrides the other"

So My next thought was to add an @Override notation.
The moment I do that it gives me the following error:"method does not override or implement a method from a supertype"

At this point I'm really confused and I've got no clue how the process methods works.
If somebody could please point me in the right direction to where I can find a tutorial about this or explain it to me, it would be really helpfull.

Thanks in advance,
Dirk

Can you post a small code with the error so that it can be compiled and generate the error message?
Your two lines of code won't compile.

There are no errors but the process method is never executed.

The API document explains well enough, that is, the process method is called by the publish() method which should be invoked from the doInBackground() method. Consult the Java API document for more details.
