如何在Java中将数值分配给JRadiobuttons并将其用作乘法器？

我想用文本字段和单选按钮制作一个简单的计算器。我已经有3个文本字段和一个“计算”按钮，动作侦听器正在工作。但是现在我想添加3个新的单选按钮分组，将值1、10和1000作为相互排除的乘数（我希望它们将最终结果相乘，但我只想使用

JButton

作为动作执行器，而不是单选按钮）

代码的相关部分如下所示：

JButton btnNewButton = new JButton("calculate!");
btnNewButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {
        double x, y, z, result;

        x= Double.parseDouble(textField.getText());
        y= Double.parseDouble(textField_1.getText());
        z= Double.parseDouble(textField_2.getText());
        result = x * y * z;

        textField_3.setText(Double.toString(your result is));   
    }
});

您可以将JRadioButtons与ButtonGroup一起使用，如：

final ButtonGroup group = new ButtonGroup();

final JRadioButton btn1 = new JRadioButton("1");
final JRadioButton btn10 = new JRadioButton("10");
final JRadioButton btn1000 = new JRadioButton("1000");
group.add(btn1);
group.add(btn10);
group.add(btn1000);

...

        public void actionPerformed(ActionEvent arg0) {
            double x, y, z, result;

                x= Double.parseDouble(textField.getText());
                y= Double.parseDouble(textField_1.getText());
                z= Double.parseDouble(textField_2.getText());
                result = x * y * z;
                if (btn10.isSelected()) result *= 10;
                if (btn1000.isSelected()) result *= 1000;

                textField_3.setText(Double.toString(result));
        }

                if (btn1000.isSelected()) result *= 1000;

                textField_3.setText(Double.toString(result));
        }
