Here is the full problem, but I just need assistance with lines marked as (1) and (2).

Operation

This is a java application that simulates a vending machine that dispenses soft drinks.

The Quarter button deposits $0.25.

The Dollar button deposits $1.00.

The label indicates the current credit.

The Refund button refunds the customers credit.

The slot buttons display the name of the product currently loaded in one of the vending machines six slots. The example above shows that the vending machine is loaded with Pepsi, Diet Pepsi, Mountain Dew, Dr. Pepper, Root Beer, and Water.

When the program starts, the six slot buttons are disabled. The program enables these buttons when the user has a credit of at least $1.00 (the cost of one item).

If the user clicks one of the slot buttons, the program displays a dialog box that tells the user to enjoy the beverage. For example, Enjoy your Diet Pepsi.

If the user clicks Refund, the program displays a dialog box that asks the user to take his or her change. For example, Please take your change of $1.25.

Specifications

You may design any classes you wish to use for this application. For example, you may want to create a class that defines a vending machine or a beverage.

Each slot in the vending machine can hold up to 10 bottles. The application should keep track of how many bottles are available in each slot and display a dialog box with the message Out of Stock if the user selects a beverage thats out of stock.

Disable the beverages button if the beverage is out of stock

(1) Create a report button on this page that can be clicked that will show the current sales of sodas (Soda name, Qty & Revenue). The report should be implemented by using a second jframe (Java) or Acivity(Android) and have a button to return the user to the first form.

(2) All data should be stored permanently such that if the application is stop/closed and re-opened the Soda Machine will still have the correct inventory. Here is the code that I am already working with:
