(3) Event Handling Adjust the code so that: the Buy button is enabled whenever something is selected from the Products list. whenever the Buy button is pressed, the name of the item selected (i.e., just the name, not the other data) from the Products list will appear in the Shopping Cart list. at any time, the Total Price field should always show the total price of all items currently in the shopping cart. Make more changes so that the Return button is enabled whenever something is selected from the Shopping Cart list. whenever the Return button is pressed, the selected item is removed from the shopping cart. the Checkout button is disabled whenever the ShoppingCart is empty and enabled otherwise. When the Checkout button is pressed, the following should happen: the Shopping Cart contents should be packed using the model's packBags() method. the Shopping Cart list should display the packed items, showing the description of all Carryable items (i.e., GroceryBags and unpacked Groceryltems) the Buy and Return buttons should be disabled and the Products list should be disabled. the Checkout button should have its text changed to "Restart Shopping" and should remain enabled regardless of whether or not anything is in the cart. A receipt for the items purchased should be printed to the System console showing each item's description and price, appropriately aligned as shown below. The total should also be shown.
