调用 ArrayLists 中的 accountNo、accountName [英] Calling accountNo, accountName in ArrayLists

问题描述

我有一个 BankAccount 类，它由 accountNo 和 accountName 的Getter 和 Setter"组成.另外，我有一个 JFrameNewAccount，它将添加新帐户并将其保存在 ArrayLists 中.输入将来自文本字段和单选按钮.

i have a class BankAccount, which compose of 'Getter and Setter' of accountNo and accountName. Also, I have a JFrameNewAccount which will add new accounts and save it in a ArrayLists. Inputs will be coming from textfields and radiobuttons.

在我的 JFrameNewAccount 中，我有一个方法:

In my JFrameNewAccount, i have a method:

ArrayList<BankAccount> list = new ArrayList<BankAccount>();

在 btnSaveActionPerformed 事件中，我有这个:

In, btnSaveActionPerformed event I have this:

list.add(txt_accountnumber.getText());
list.add((txt_accountname.getText()));

它给了我一个错误没有找到适合 add(String) 的方法"我知道是ArrayList的原因，如果我用ArrayList，好像还可以，但是我不知道如何调用提款框里的账号.

and it gives me an error 'No suitable method found for add(String)' I know it is because of the ArrayList, and if I used ArrayList, it seems okay, but i don't know how can i call the account number in my withdraw frame.

推荐答案

您的 list 不允许您在其中添加字符串.

Your list does'nt allow you to add Strings in it.

我想，您需要在那里准备一个对象，其中包含来自 textfields 的值.

I guess, you need to prepare an object there with the values coming from the textfields.

BankAccount account= new BankAccount();
account.setAccountnumber(txt_accountnumber.getText());
account.setAccountname(txt_accountname.getText());
list.add(account);

每次新用户进入详细信息创建一个对象并保存到list.

Each time a new user entered the Details create one object and save into the list.
