    Default Del boy dealership

    Hi, since I'm new to java I already failed my first assignment this is my referral assignment I'm only set to gain about 49% Grade mark A, so as a lot of people are probably used to seeing this assignment I was wondering if someone could help me real quick

    "User Requirements Set A
    1. Car records:
    a. add a new car
    b. for a given registration number print the carís details
    c. print a list all cars that are for sale (i.e. where the price paid for is zero)"

    Now I've done what I'm guessing is correct but I can't get BlueJ to recognise a damn increment and not quite sure what I'm doing wrong hopefully maybe one of you guys can help me out.

    So this would be my Main part of the program




    Any help, I would be greatful

    /**

    public class Main
    {
     
        private ArrayList<Cars> cars;// Array for storing cars;

    not quite sure what I'm doing wrong
    If there are error messages, copy the full text and paste it here.
    If the program's output is not what you want, post the output and add some comments showing what you want it to be.
    If you don't understand my answer, don't ignore it, ask a question.
