What I have tried:

        String ph=PhNoTxt.getText();
        String email=EmailAddTxt.getText();
        PrintWriter writer=new PrintWriter(new BufferedWriter(new FileWriter("Customer detail.txt",true)));
        writer.println(id);
        writer.println(name);
        writer.println(ic);
        writer.println(ph);
        writer.println(email);
        writer.close();
        JOptionPane1.showMessageDialog(this, "Register customer was successful");
        m.setVisible(true);
        this.setVisible(false);
        }
        catch(Exception e)
        {
            JOptionPane1.showMessageDialog(this,"All fields must be completed in order to register");
        }
    }

推荐答案

在您的代码中，您已经将文本字段值保存到文件中（您保存了 getText 方法返回的字符串。

通常，单选按钮表示允许选项的值，即枚举项。您可以将整数值保存对应于选择的项目。

In your code you have already saved text field values to a file (you saved the string returned by the getText method).
Usually a radio button represents the value of an allowed option, i.e. an item of an enumeration. You could save the integer value correspondig to the choosen item.
