Object within Constructor with a method?

Question

Hi,
Just trying to understand java code example and its various parts. i.e fields, constructor, methods etc. It is a Blackberry application.
I am mainly wondering about the part with the " HorizontalFieldManager(USE_ALL_WIDTH )". This has a method attached to it. So if this is the case it is an 'Object' within the UserInterface 'Constructor' that has a 'Method'?
And the semicolon at the end is not normally present on Methods is it?
Thanks.
//// EXAMPLE CODE ///
public class UserInterface extends UiApplication {
public static void main(String[] args) {
UserInterface theApp = new UserInterface();
theApp.enterEventDispatcher();
//constructor for UserInterface?
public UserInterface() {
pushScreen(new UserInterfaceScreen());
//UserInterfaceScreen class
final class UserInterfaceScreen extends MainScreen {
//fields or variables
HorizontalFieldManager _fieldManagerTop;
String _exchange, _convertedStr, _euroStr;
double _euros, _pounds, _converted;
int displayed = 0;
//constructor?
public UserInterfaceScreen() {
super();
LabelField title = new LabelField("Euro Calc",LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
setTitle(title);
_fieldManagerTop = new HorizontalFieldManager();
// An object with a method?
_fieldManagerGround = new HorizontalFieldManager(USE_ALL_WIDTH ) {
protected void paintBackground(Graphics graphics)
graphics.setBackgroundColor(0x00382B79);
graphics.clear();
super.paint(graphics);

Hi,
this is a way to override the HorizontalFieldManager.paintBackground method whithout declaring a subclass inheriting from HorizontalFieldManager. See ANONYMOUS CLASSES in the following Link.
