Yes you can have an ArrayList which can contain JComboBox type elements 是的，您可以拥有一个可以包含JComboBox类型元素的ArrayList

You can create ArrayList like this: 您可以像这样创建ArrayList：

  List<JComboBox> comboBoxList = new ArrayList<>(); // you can also provide capacity here

And then you can create JComboBox instances by using any of the constructors 然后，您可以使用任何构造函数创建JComboBox实例

  JComboBox combo1 = new JComboBox();
  // set properties of JComboBox here

And then you can add this to your comboBoxList by 然后您可以将其添加到您的comboBoxList

  comboBoxList.add(combo1);
