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.

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
