I'm currently in the process of creating a shopping cart simulation. The main GUI consists of two lists, one is a list of the inventory. (products stored within a .dat file which is automatically loaded upon launch) The other is blank and is to model my shopping basket. The idea is to be able to scan items from my inventory into the checkout basket. As this is happening i want a text field i created to dynamically update with the cost of all the items in the basket.
Below is the method for my scan button, which is supposed to perform the above :
Currently however scanning the item will add it to the list but print strange results in the total. (Adds 5.5 for each item regardless of their actual value**). It will also print a line under the item name as such javax.swing.JList[,0,0,344x326,layout=java.awt.BorderLa... .
Below are the classes for my CartItem and ItemList if they may help. Thank you.
-Cart Item
-ItemList
