Hi All

I new to java so bare with me if this is a ridiculously simple question but I am curious about this method call which has {code} being taken in - see code below for an example in the method addSelectionListener. What is the purpose of this? I have been looking through docs for an explaination but cant seem to find what this practice is called never mind any useful information.

    setStatusLine.addSelectionListener(new SelectionAdapter() {
        public void widgetSelected(SelectionEvent e) {

            String message = "I would like to say hello to you.";
            if (pressed) {
                message = "Thank you for using me";
            }
            setStatusLine(message);
            pressed = !pressed;
        }
    });

Thanks for any help or insights that can be offered
