This setup is using the concept that my listview contains information regarding an object, I would therefore add this extra string as an attribute to my customer class.
@@Randomcode_0 my problem is apparently caused by the fact that I store the data for the table in an observable list and when I remove the last element from it, it is removed, but not removed from the table and loaded again into the list, if I remove from the table, then it is not removed from the list
hello, I need help please ! do we need to use MySQL to make the tableView work ?? for my case I need to make my tableView do sum calculations for me like (sum, average, max/min ...etc) just like we usually do with Microsoft Excel , can I??
So…in the Customer class would it not be easy to use the Wrapper Class “Integer” to begin with..instead of the Primitive “int?” Wouldn’t this avoid the later using “ParseInt” to the “age” convert into an “Object” later? Just asking… thanks
It is an excellent question. In this case, I do not think it would change anything as we use 'Integer.parseInt(ageInput.getText())' because we get the age as a string from a TextField. The main advantage of primitives is that they can't be null, which helps avoid null-related problems. However, it might be possible to create a number input field that can prevent the need for this casting.
thank you for the vedio but the delete method only delete the value in sceen builder not in the data Base, Can you give me a hint about this ? Have a good day
We would need to set up some CRUD connection which would often be placed inside a singleton, which would handle the database connection. for the database connection, a way to do it would be to change your data in the database and then reload the tableview using the data in the database.
I have a text field to search for data inside the table ,but it only works when I click on the table. I have used the function table. requestfocus() but its not working Help pls 💚

You can use the tableview without any SQL, it is used to display the data from a java object. you can extract all this information and then use java to calculate whatever you want, but you cant use a plain table view to do complex calculations.
@@Randomcode_0 thank u so much for answering ! it really means a lot to me. I'm a begginer in java.. so after extracting the data.. i can do the calculation.. Can i make on of the TableView 's cells show the result of the calculations ? please tell me more thank you again !
@@katt2478 The table view is fixed where every row will contain the same information. Therefore I think it would be simpler to just have some text display your calculations, but everything is possible.

thank you you really helped me .God blessed you
You're very welcome! I'm happy to hear that I could be of help to you.
hello, did you have problem with deleting last row of the table? I can delete all the tables except the last one, how can i fix this?
Just tried to rerun this old project, and I am able to remove all elements I add to the TableView, including the last one.

Yes we can populate the tableview from mysql database. And then do some calculations.

And can u show how to edit data in tableview?
I will add “edit tableview data” to my list of things to do.
Take a look at my newst video regarding "Edit TableView: ruclips.net/video/3s8s0vyfLV8/видео.html
How to focus this table?
You can click an item on the table or use TAB to interact with the table, however, I am not quite sure what you mean?
I have a text field to search for data inside the table ,but it only works when I click on the table.
I have used the function table. requestfocus() but its not working
