Program Plan Intro

  To implement a program that simulates airplane system

Program plan:

• In the file “Seat.java”, create a class “Seat”,
  • Declare the variable.
  • Define the constructor.
  • Define the method “addCost()” to add a charge to a seat.
  • Define the method “getCharges()” to get the charges for this seat.
• In the file “Airplane.java”, create a class “Airplane”,
  • Initialize necessary variables.
  • Define the constructor to construct an Airplane object.
  • Define the method "addCharge()" to add the cost.
  • Define the method “getSeatingCharges()” to get a string displaying the charges per seat.
• In the file “AirplaneMenu.java”, import necessary packages, and create a class “AirplaneMenu”,
  • Declare a variable.
  • Define the constructor construct an “AirplaneMenu” object.
  • Define the method “run()” to run the system,
    • Create necessary array to hold snacks and drinks.
    • Execute loop if not done.
    • Prompt the user a command.
    • Convert to uppercase.
    • If the input command is equal to “O”,
      • Prompt and get the row number.
      • Prompt and get the seat number.
      • Get the snack item, and check if is first item,
        • Call the method “addCharge()”.
      • Get the drink item, and check if is first item,
        • Call the method “addCharge()”.
      • Check if drink is either second or third item,
        • Call the method “addCharge()”.
      • Check if row number is “<6”,
        • Increment the snack.
        • Increment the drink.
      • Otherwise,
        • Increment another snack array.
        • Increment another drink array.
    • Otherwise, check if the input command is equals to “S”,
      • Display the order.
    • Otherwise, check if the input command is equals to “Q”,
      • Quit the application.
        • • Define the method “getSnack()” to get the snack item from the user.
          • Define the method “getDrinkk()” to get the drink item from the user.
• In the file “AirplaneOrderingSystem.java”, import necessary packages, and create a class “AirplaneOrderingSystem”,
  • Define the method “main()”,
    • Create an object for “AirplaneMenu”.
    • Call the method “run()”.
