I am making a pizza program and most of the program works. I have made an order button that will output the total price of the order. The reset button that I made makes the JTextArea output $0.00, but if I press the order button to make another order, the program does not add the new amount to zero. For example, if I make an order that totals $5.00, but I want to make another order after resetting, the price for the new order will be added on to the previous order's price. Here is the code. This is a JApplet program. Any help would be greatly appreciated! Can you please tell me why the price will not reset? I have posted the code so that you can try the program for yourself. FYI, this code was made in BlueJ as I am a beginner with Java.
