Display all the items I have ordered
问题
如何在“销售报告文件”中显示我订购的所有商品？例如，每当我订购2个曲奇，它都会显示在销售报告文件中。我目前有这段代码...
private final Dispenser candy = new Dispenser(100, 50);
private final Dispenser chips = new Dispenser(100, 65);
private final Dispenser gum = new Dispenser(75, 45);
private final Dispenser cookies = new Dispenser(100, 85);
public int products;
private final JButton candyB;
private final JButton chipsB;
private final JButton gumB;
private final JButton cookiesB;
private class ButtonHandler implements ActionListener {
public void actionPerformed(ActionEvent e) {
switch (e.getActionCommand()) {
case "Exit":
System.exit(0);
case "Candy":
sellProduct(candy, "Candy");
products++;
break;
case "Chips":
sellProduct(chips, "Chips");
products++;
break;
case "Gum":
sellProduct(gum, "Gum");
products++;
break;
case "Cookies":
sellProduct(cookies, "Cookies");
products++;
break;
case "Sales Report File":
JOptionPane.showMessageDialog(null, "售出的商品列表：" + DISPLAY ALL THE ITEMS ORDERED,
"销售报告 ~ ", JOptionPane.PLAIN_MESSAGE);
break;
}
}
}
（注意：DISPLAY ALL THE ITEMS ORDERED 部分应替换为您实际的代码来显示已订购的商品列表。）

如果您想要一个您已订购物品的文本列表，您只需创建一个 ArrayList<String>，每次点击一个产品时，执行 list.add('Cookies') 或其他产品的名称，具体取决于开关。通过这种方式，您将获得一个按时间顺序排列的产品列表。
输出将会类似于：
Cookies,
Candies,
Candies,
Gum,
Chips,
Gum,
...
英文:
If you want like a text list of what you have ordered, you can simply create an ArrayList<String> and every time you click on a product you do list.add('Cookies') or whatever the product is, depending on the switch. In this way you have a list ordered by time-ordered products.
The output would be something like:
Cookies,
Candies,
Candies,
Gum,
Chips,
Gum
...
