this was a homework assignment I had that was previously done. As in I did the best I could, and turned in what I had and that got graded. My assignment was to create a GUI that would let you chose what vehicle type you had (compact, mid-size, luxury, suv) as that determined the size of your gas tank, what type of gas you wanted to use (super unleaded, unleaded, leaded, diesel) as that determined the price per gallon, and the distance you wanted to travel. It would then calculate out how much it would cost. I have the algorithm for calculating all that, but my class was teaching Swing which makes little to no sense to me, and I decided to try and make remake this using JavaFX. My issue now is that I cannot get the project to compile as there is an issue with a constructor, and I don't know how to get it so it uses the calculate() method when the calculate button is pressed. Im not so much worried about the layout of the program at this point because I can't see it. I will get to that later. Anyone able to help me out at all? Like I said, this was an old homework assignment that has already been graded, I just wanted to try javaFx instead of Swing.
