Creating a List of TableColumn, java swing

I've seen a few examples on this site where people working with JTables declare the following:

 List<TableColumn> columns = new ArrayList<TableColumn>();

I'd like to do this too, as my goal is to create a list that will store columns that are hidden from the user (I need the list so that I can un-hide the columns later if need be).

However, when I try the above eclipse tells me:

The type List is not generic; it cannot be parameterized with arguments

Can someone tell me how to fix this? Or suggest another option?

You can check out Table Column Manager. It provides hide/show functionality for the TableColumns.

It is designed to allow the user to control which columns are displayed/hidden but you can turn that off by using setMenuPopup(false).

You must have imported the wrong List class.

Make sure you have java.util.List; As opposed to java.awt.List; or some other list.
