Thread: Getting items from a table/checkboxes

Hi,
i have a Java computer shop assignment, a user selects the components he/she requires for a laptop or desktop and then presses the submit button where the total price is calculated and displayed to the user.

I have hard coded the prices for each component in a table, but am unsure as to how to "get" the users selections and how to add the prices up? or how to put that into code rather.

[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 */
public ShopFrame() {
initComponents();
}

Hi sorry for the confusion, i did use

tags?

I have attached the files in a zip....i am using netbeans so there is a whole lot of code in the middle of the program that is just design code generated by the program so i just posted the relevant bits.

private void bSubmitActionPerformed(java.awt.event.ActionEvent evt) {

TO DO CODE HERE //getValueAt() (for the table?)

}

I have set up a computer shop that the user selects components for their desired computer i hard coded all the details in a JTable which contains the price of each component. Firstly they select whether they want a laptop or desktop from a drop down toolbar menu and then what CPU they want in it from a combobox.

And then the price is in the table of each component so i need to get all the selected components from the user and then return a total price for them.

hope that is clearer but i have included the JAVA files built with netbeans....it compiles fine there is just so much code that netbeans generates i was trying to keep it simple but..
