    Question What kind of object instantiation is this?

    Hi!

    I'm new to Java and I was reading up about SwingWorker when I came across this code.

    SwingWorker worker = new SwingWorker<ImageIcon[], Void>() {
        @Override
        public ImageIcon[] doInBackground() {
            final ImageIcon[] innerImgs = new ImageIcon[nimgs];
            for (int i = 0; i < nimgs; i++) {
                innerImgs[i] = loadImage(i+1);
            }
            return innerImgs;
        }

    What is this new <> stuff? Please tell me what it's called so I can learn about it. Or give me a link to an online tutorial.

    this new <> stuff?
    That's Generics.
    Go to this site: The Really Big Index
    and do a Find for Generics
