[DrJava] the cool stuff you can do in the interactions pane

[Brian S. <bs...@bs...>]

feature tip of the day #1: did you know you can make anonymous inner class
instances in the repl?

> final JFrame copy = frame;

[...]

> ActionListener listener = new ActionListener() { public void
actionPerformed(ActionEvent ae) { copy.hide(); } };
> button.addActionListener(listener);

related tip #2: In said anonymous inner class instances, you can reference
final variables that are declared at top-level in the interactions pane.

Pretty cool.
