JTable and removeAll behavior


JTable and removeAll behavior

To fix the issue you can do You want to change your JTable's model, not call removeAll(). Note that if you go to the JTable API you'll see that the removeAll() method is not a method specifically of JTable but rather of Container, one of JTable's parents. The method does not do "JTable-specific" actions, but rather removes all components held by a container, such as components held in a JPanel for an example.
To empty out a JTable you will want to do one of the following:

help you fix your problem The directions you are following are bad as there's no need to fiddle with renderers or editors (and by the way, your problem is that you changed the renderer without changing the editor). All you have to do is in your TableModel class, override the getColumnClass(int index) method and have it return Boolean.class for the column that needs check boxes. That's it. The JTable will automatically use a checkbox both for the column's renderer and editor solving your problem in a very easy way. Of course it should go without saying that the data for that column must be Boolean for this to work.

hope this fix your issue You have basically created undefined behavior since your sets have different criteria of equality. Combining collections in any way can only work if they have the same. You are basically violating the contract that A.equals(B) must yield the same result as B.equals(A).
Suspicious Behavior From ListView.getItems().removeAll()

Suspicious Behavior From ListView.getItems().removeAll()

it fixes the issue When you remove a selected item, the selection will be updated so that some other item will be selected. When the selection is updated, this has the side effect of updating the list returned by listView.getSelectionModel().getSelectedItems(). This interacts badly with the List.removeAll method.
Suppose we have targetList.removeAll(removeList). What happens is that for each element in targetList, the code asks, "does this element appear in removeList?" If it does, the element is removed from targetList. This has a side effect on removeList, which changes the behavior the next time around the loop.
code :
list.getItems().removeAll(new ArrayList<>(list.getSelectionModel().getSelectedItems()));

hop of those help? After searching and reading correctly the documentation about TreeSet, it turns out that:
code :
set1.removeAll(set2);
set1.removeAll(new HashSet<>(set2));
