    You can’t assign a uniques name to every component you dynamically generate.

    As you define the text fields you need to add them to a List (or some other data structure). Then you can access the textfields individually from the List.

    List<JTextField> textFields = new ArrayList<JTextField>();
    
    for (int i = 0; i < 10; i++)
    {
        JTextField textField = new JTextField();
        textFields.add( textField );
        somePanel.add( textField );
    }
    
    somePanel.revalidate();
