Question

I am making an application for inserting examination marks into a database. I have managed to use a JTable to display data from the database but now i want to use the same JTable to insert data to the database. how i do that?I will appreciate any assistance given

Answer 1

You could:

1) Allow the user to select a row they want to edit.

2) Allow the user to click a button that opens a new window with textfields that are populated with the data from the selected row.

3) Add a "save" button to this newly opened window which, when clicked, queries the database and "updates" where xyz = row that has been selected.

Answer 2

How are you changing the TableModel from you JTable ? what structure are you using, if you are using an ArrayList to fill your Jtable you could use the same structure in order to edit your elements, just create a class that implement a TableModelListener , and override the tableChanged method in order to make the update

Edit: ok so you have to get the model from your JTable,

tbl_report.getModel().getValueAt(row, column); and this will give you the value from a specific cell, since you want all the JTable Values you could make this using a for (indeed two for's) something like this:

 ArrayList<Object> value= new  ArrayList<Object> ();
    for (int column = 0; column < resumenTable.getColumnCount(); column++) {
        for (int row = 0; row < resumenTable.getRowCount(); row++) {
         value.add(resumenTable.getModel().getValueAt(row, column));
        }
    }

You will have to cast the ArrayList elements in order to construct your query
