Getting selected values from a form
Hi,
i have constructed a JFrame for a computer shop (an assignment)the user has to select the components needed relating to buying a laptop or a desktop. When he/she has selected these the price of each is then totalled up and the total displayed on the screen.
Each component is presented either as a menu item or combobox.
I am not sure as to how to "get" the prices to add them up? I have at present the values in a table for a desktop CPU, and a laptop cpu with a view to adding all other component prices so that the prices are all in one place in a JTable.
The total price is displayed when the user presses the submit button.
I have also attached the file so that you can see properly what i am trying to do.
Code:
package ecsecomputers;
import javax.swing.JLabel;
import javax.swing.JComboBox;
import javax.swing.JButton;

public class ShopFrame extends javax.swing.JFrame {
/** Creates new form ShopFrame */
