Hi, I am currently finishing up a project for Java. I have the car.java and carlot.java classes finished, I just need the main class to implement into the GUI that sorts and does the math. If it could be finished before 11:59 pm on the 30th, that would be amazing.
The project should:
Be a WidgetViewer program that allows GUI control of the Car Lot and individual Car information
Use event handlers to indicate a user clicking a button to add or sell cars
Allow a user to add a car with a given identifier, initial mileage and fuel consumption in miles per gallon (MPG), the cost of acquiring the new car, and the price the new car will be sold for. All new cars have a status of is not sold
Be implemented as multiple classes with multiple instances of some classes
Remove or sell a car from the inventory using its identifier, changing its status from is not sold to is sold and adding a field for profit where profit made is displayed.
Display the lots inventory both in the order that the cars were entered and in the order of best-MPG to worst-MPG; In descending order.
Display the car with the best MPG and the highest mileage.
Display the average miles per gallon for the entire fleet
Display profit (price - cost) from sold cars
The files are as follows:
Car.java

private int cost;

Please, this is my third time asking for help on this. I have done most of the hard work, I just need help on the main class. It is similar to the other car lot programs on this website. I know it can be done on time. Thank you.
