TableRowSorter<TableModel> sorter = new TableRowSorter<TableModel>(tblProduct.getModel());
tblProduct.setRowSorter(sorter);

List<RowSorter.SortKey> sortKeys = new ArrayList<>();
sortKeys.add(new RowSorter.SortKey(6, SortOrder.DESCENDING));
sorter.setSortKeys(sortKeys);

It is sorting it in order by the first number of the integer rather than the whole number, what is the easiest way of fixing this?

i.e. output like:

9
8
8
5
2
17
12

Suggests also that you have a 'wrong' model. The column contains a String and not Integer – g00se
Unfortunately, I rarely work with JTables. I would guess you either need to change the model for the sort column to Integer like g00se intimated, or find a way to alter the comparator (if possible) to convert the String to an Integer for sorting purposes. – WJS
The Oracle tutorial, How to Use Tables, will show you how to use JTables. – Gilbert Le Blanc
You need to: 1) store Integer objects in the model and 2) override the getColumnClass(...) method of the model to tell the table what the class of each column of data contains. See: stackoverflow.com/questions/34026013/… – camickr
