class Rb extends JFrame {
Rb (){
JRadioButton Chocolate = new JRadioButton(\"Chocolate\");
JRadioButton Strawberry = new JRadioButton(\"Strawberry\");
JRadioButton Vanilla = new JRadioButton(\"Vanilla\");
ButtonGroup bG = new ButtonGroup();
bG.add(Chocolate);
bG.add(Strawberry);
bG.add(Vanilla);
this.setSize(100,300);
this.setLayout( new FlowLayout());
this.add(Chocolate);
this.add(Strawberry);
this.add(Vanilla);
Chocolate.setSelected(true);
