Hello,
I have done the code for the final part of the Java Inventory Program in my class. This is the requirements for the final code.
• Modify the Inventory Program to include an Add button, a Delete button, and a Modify
button on the GUI. These buttons should allow the user to perform the corresponding
actions on the item name, the number of units in stock, and the price of each unit. An
item added to the inventory should have an item number one more than the previous last
item.
• Add a Save button to the GUI that saves the inventory to a C:\data\inventory.dat file.
• Use exception handling to create the directory and file if necessary.
• Add a search button to the GUI that allows the user to search for an item in the inventory
by the product name. If the product is not found, the GUI should display an appropriate
message. If the product is found, the GUI should display that product’s information in the
GUI.
Here is my code and following it are the errors I am getting. Any help would be greatly appreciated!
tory Program
* This program keeps track of products and calculates and displays;
* price, name, number, quantity, and total inventory value.
