Question
Write an applet that simulates a soft drink vending machine. The simulated machine dispenses the following soft drinks: cola, lemon-lime soda, grape soda, root beer, and bottle water. These drinks cost $0.75 each to purchase.
When the applet starts, the drink machine should have a supply of 20 of each of the drinks. The applet should have a text field where the user can enter the amount of money he or she is giving the machine. The user can then click on a button to select a drink to dispense. The applet should also display the amount of change it is giving back to the user. The applet should keep track of its inventory of drinks and inform the user whether he or she has selected a drink that is out of stock. Be sure to handle operator errors such as selecting a drink with no money entered and selecting a drink with an inadequate amount of money entered.
To accomplish this, you need to create a class name Drink, use a constant for the price, and have properties to hold the inventory and the type of drink.
Make a button for each soda, each button should have a different color representing the soda, this color should also be a property of the class. When there is not enough money deposited or there are no more bottles of the selection, disable the button.
I need screenshots of netbeans from code line 1 all the way till the end please. Showing how to do it from point a to point b. Thank you
