Program Plan Intro

  To implement a program that simulates vending machine

Program plan:

• In the file “Product.java”, create a class “Product”,
  • Declare the variable.
  • Define the constructor to constructs a Product object.
  • Define the method “getDescription()” to get the description.
  • Define the method “getPrice()” to get the price.
  • Define the method “equals()” to determine of this product is the same as the other product.
  • Define the method “toString()” to format the product's description and price.
• In the file “VendingMachine.java”, create a class “VendingMachine”,
  • Declare an “ArrayList”.
  • Define the constructor to construct “VendingMachine” object.
  • Define the method "getProductType()"to get the type of products in the vending machine.
  • Define the method “addProduct()” to add a product to the vending machine.
• In the file “VendingMachineMenu.java”, import necessary packages, and create a class “VendingMachineMenu”,
  • Declare a Scanner variable.
  • Define the constructor to create a Scanner object.
  • Define the method “run()” to run the vending machine system.
  • Execute for true value,
    • Prompt the user to enter option.
    • Get the user command from the user.
    • Check if the input is “S”, show the products.
    • Otherwise check if the input is “A”, get the product items, price, and quantity from the user.
    • Otherwise, check if the input is “Q”, quit the application.
      • Define the method “main()”,
        • Call the method “run()” to run the application.
