Blueberry Muffins   $0.85
Chocolate Brownie   $1.75
French Toast        $2.25

Hot Chocolate       $1.75
Food                $2.50
 
 Thank you for your business

Then Sort the menu in alphabetic order, calculate the items prices and add a sale tax of 6% but also a local tax of 1% , then the program is suppose to read the greeting line such as << Thank you for your business >> from the file input and produce a day end report .

Done so far
I have the input and prices sorted on the left panel , I also have the day end report , the local and state tax set

What I have left
- For right now I have the prices saved in a array of static double instead of reading from a file
-Input the prices and offerings when selected in the right pane in order to calculate the subtotal price and add to both taxes in order to have the total price
- As of right now I have the program reading the greeting from a different file but would like to only use one file .

Code

public class remet extends JFrame implements ActionListener

 static double[] yourChoicesPrices = 
              {0.85, 0.80, 0.75, 2.75,
