Move a circle using arrow keys - Java
<p>I'm experimenting with JavaFX right now teaching myself how to move text and items using the arrow keys. I made a program that simply moves text around the stage if an arrow key is pressed down.</p>

<p>I would like to make a circle move around my pane instead of text. What changes must I make to move my circle using the arrow keys?</p>

<pre><code>public void start(Stage primaryStage) {
        Pane pane = new Pane();

        int dx = 50;
        int dy = 50;
        int radius = 125;

        Circle circle = new Circle(radius,dx,dy);
        Text text = new Text(20,20,"HI");
        circle.setFill(Color.WHITE);
        circle.setStroke(Color.BLACK);

        pane.getChildren().addAll(circle, text);

        circle.setOnKeyPressed(e -&gt; {
            switch(e.getCode()) {
            case DOWN: text.setY(text.getY() + 10);
            break;
            case UP: text.setY(text.getY() - 10);
            break;
            case LEFT: text.setX(text.getX() - 10);
            break;
            case RIGHT: text.setX(text.getX() + 10);
            break;
            default:
                if(Character.isLetterOrDigit(e.getText().charAt(0)))
                    text.setText(e.getText());
            break;      
            }
        });

        Scene scene = new Scene(pane, 250, 200);
        primaryStage.setTitle("Arrow Keys");
        primaryStage.setScene(scene);
        primaryStage.show();

        text.requestFocus();
    }
</code></pre>
