To capture the option of a JRadioButton , one of the ways would be to implement in some way the interface ItemListener which has as abstract method itemStateChanged(ItemEvent e) .

To generate the event we would do it with the JRadioButton and the addItemListener(ItemListener l);

method

miRadioButton.addItemListener(new ClaseQueImplementaItemListener());

Where ClaseQueImplementaItemListener() would be the receiving class of the event .

And to know the exact radiobutton pressed .. inside the method itemStateChanged ()

if (miRadioButton.isSelected()) {
        new VentanaResultados();
}

Also you could do with an anonymous class in this way ..

miRadioButton.addItemListener(new ItemListener() {
        @Override
        public void itemStateChanged(ItemEvent e) {
            new VentanaResultados();
        }
    });
