我正在尝试用javafx构建一个收据应用程序……如何在单击按钮时将标签对象添加到整数表字段中

我已经编写了每一个应该实现这一点的代码，比如InvoiceEntry.java和它的.fxml。请大家帮帮我，我该怎么处理这个问题。如果你愿意，我可以给你看其他代码，因为我不知道如何使用stack exchange一次发布所有代码

这是代码的完成

InvoiceEntry.java

  //this is the button that add objects to the table cells

@FXML
private void OK01(ActionEvent event) 
{
 rImg20.setVisible(false);
 tv.setVisible(true);


 String combo022 = combo02.getValue().toString();
 Integer result = Integer.valueOf(prCombo01.getText());
 del01.setVisible(true);

 data.add(new InvoiceEntry(
 (String) combo01.getValue(),
 combo022,   
 (String) combo03.getValue(),
 (String) combo04.getValue(),

 (Integer)prCombo01.getText()));       //but i cant get this label to add to the    
                                                                 integer column (price) of the table 
}

FXML

Java是一种强类型语言，您不能将字符串强制转换为整数，但您可以使用户，但是您应该准备好，如果字符串实际上不是整数，解析可能会出现NumberFormatException

还有一件事，price可能不是int/Integer，很可能你想用它来代替，但是，请千万不要用double/double或float/float来表示任何与钱有关的东西！。可以使用

从字符串创建BigDecimal。您需要向我们展示如何声明表。代码不够。我需要一个标签，其整数值只需单击一个按钮即可添加到表中
