    public void startApp() {
        Display.init(this);
        Form f = new Form("Lwuit TabbedPane");
        f.setLayout(new BorderLayout());

LWUIT: ButtonGroup

The ButtonGroup component manages the selected and unselected states for a set of
RadioButtons. For the group, the ButtonGroup instance guarantees that only one
button can be selected at a time.

import javax.microedition.midlet.*;
import com.sun.lwuit.*;
import com.sun.lwuit.events.*;
import com.sun.lwuit.layouts.BorderLayout;

public class LwuitButtonGroup extends MIDlet implements ActionListener {
    public void startApp() {
        Display.init(this);
        Form f = new Form("Hello, MIDlet in LWUIT!");
        Command exitCommand = new Command("Exit");
        f.addCommand(exitCommand);
        f.setCommandListener(this);

        f.setTitle("ButtonGroup");

        RadioButton radioButton1 = new RadioButton("Radio Button 1");
        RadioButton radioButton2 = new RadioButton("Radio Button 2");
        RadioButton radioButton3 = new RadioButton("Radio Button 3");
        ButtonGroup buttonGroup1 = new ButtonGroup();
        buttonGroup1.add(radioButton1);
        buttonGroup1.add(radioButton2);
        buttonGroup1.add(radioButton3);
        f.addComponent(radioButton1);
        f.addComponent(radioButton2);
        f.addComponent(radioButton3);

        RadioButton radioButtonA = new RadioButton("Radio Button A");
        RadioButton radioButtonB = new RadioButton("Radio Button B");
        ButtonGroup buttonGroup2 = new ButtonGroup();
        buttonGroup2.add(radioButtonA);
        buttonGroup2.add(radioButtonB);
        f.addComponent(radioButtonA);
        f.addComponent(radioButtonB);

        f.show();

    }

    public void pauseApp() {}
    public void destroyApp(boolean unconditional) {}
    public void actionPerformed(ActionEvent ae) {
        notifyDestroyed();
    }
}

LWUIT: GridLayout

A GridLayout object places components in a grid of cells. Each component takes all
the available space within its cell, and each cell is exactly the same size.

 GridLayout gridLayout = new GridLayout(3, 2);
        f.setLayout(gridLayout);
        f.setTitle("GridLayout");
        
        f.addComponent(new Button("Button 1"));
        f.addComponent(new Button("Button 2"));
        f.addComponent(new Button("Button 3"));
        f.addComponent(new Label("Label 1"));
        f.addComponent(new Button("Button 4"));

LWUIT: FlowLayout

The FlowLayout class provides a very simple layout manager that is the default
layout manager for Container objects.
The FlowLayout class puts components in a row, sized at their preferred size. If the
horizontal space in the container is too small to put all the components in one row,
the FlowLayout class uses multiple rows. To align the row to the left, right, or center,
use a FlowLayout constructor that takes an alignment argument.

        FlowLayout flowLayout = new FlowLayout();
        f.setLayout(flowLayout);
        f.setTitle("FlowLayout");
        
        f.addComponent(new Button("Button 1"));
        f.addComponent(new Button("Button 2"));
        f.addComponent(new Button("Button 3"));
        f.addComponent(new Label("Label 1"));
        f.addComponent(new Button("Button 4"));

LWUIT: BoxLayout

The BoxLayout class puts components either on top of each other or in a row.

        BoxLayout boxLayout = new BoxLayout(BoxLayout.X_AXIS);
        f.setLayout(boxLayout);
        f.setTitle("BoxLayout: BoxLayout.X_AXIS");
        
        Button button1 = new Button("Button 1");
        Button button2 = new Button("Button 2");
        Button button3 = new Button("Button 3");
        f.addComponent(button1);
        f.addComponent(button2);
        f.addComponent(button3);

        BoxLayout boxLayout = new BoxLayout(BoxLayout.Y_AXIS);
        f.setLayout(boxLayout);
        f.setTitle("BoxLayout: BoxLayout.Y_AXIS");
        
        Button button1 = new Button("Button 1");
        Button button2 = new Button("Button 2");
        Button button3 = new Button("Button 3");
        f.addComponent(button1);
        f.addComponent(button2);
        f.addComponent(button3);
