        String selected = "";

        if (rbJava.isSelected()) {
            selected = "Java";
        } else if (rbPython.isSelected()) {
            selected = "Python";
        } else if (rbCpp.isSelected()) {
            selected = "C++";
        }

        lblResult.setText("You selected: " + selected);
    }
