So i am writing this code for my programming class and need help getting the "Get fruit Item" "Get Drink Item" and the "Delete Ordered Item" to work.

i need the "Get fruit Item" and "Get Drink Item" buttons to add the item to the "Items Ordered" panel to the right, and the "Delete Ordered Item" button to remove the item from the list. I already have it so that when you double click it will add/ delete the item, but the button itself wont work.

Lastly i need to add a Clear All button next and to the right of the item delete button and program the button to remove all the items in the ordered list and reset the running total to zero when the button is clicked.

This is my code so far:

import java.awt.*; import java.awt.event.*;
