- if you want to add an item and let the program sort the whole set, you should use, as already suggested by mjcoon, an ArrayList. With this control you can add or insert and then sort the items, and then clear the combobox and fill it with the items in the sorted ArrayList.
Best regards.
You will need at least one place to store the data, so saving the table will be not a bad solution....will I have to save the table as csv everytime??...
Attached my version.
What's the problem putting the default values into a given csv file?Specci, unfortunately your version doesn't run well the first time if there is no csv file. The Table must be initialized, otherwise you loose the first default values of the combobox.
Of course there is no problem to generate a csv file seperately.What's the problem putting the default values into a given csv file?
And I like to separate technical from non technical data so you can configure the behaviour of the program without changing the code.I have the habit to include default values in the source code which are used if the parameter file doesn't exist.
:sign0156:As usual there are different ways doing things.

Using 3 ArrayLists would be more suitable. You can add, insert, remove and sort the data independently and fill the Comboboxes from the ArrayLists. To save the data you can use a simple text file, the content of each ArrayList is saved one after the other.
