將所選的單選按鈕值和文本字段值保存到文件中

Question

我可以通過GUI窗口知道如何將選定的單選按鈕值和文本字段值保存到文件中？

的形式看起來像this

我的代碼：

private void SaveButActionPerformed(java.awt.event.ActionEvent evt) {           
    try{ 
    File f=new File("Customer detail.txt"); 
    String id = this.CusIDTxt.getText(); 
    String name=NameTxt.getText(); 
    String ic=ICNoTxt.getText(); 
    String ph=PhNoTxt.getText(); 
    String email=EmailAddTxt.getText(); 
    PrintWriter writer=new PrintWriter(new BufferedWriter(new FileWriter(f,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(IOException ioe) 
    { 
     JOptionPane1.showMessageDialog(this,"All fields must be completed in order to register"); 
    } 
}

你叫一個文件作家，但你不叫方法來寫它。例如，你可以嘗試writer.write（name）。它會將輸入寫入文件。你可以看到這個API的文檔https://docs.oracle.com/javase/7/docs/api/java/io/PrintWriter.html
