This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I was attempting to write a code which would create a car class. Then display two cars on a screen. The problem is I keep getting a couple errors.
It seems that the car constructor is not being created before the CarComponent class creates the object. But I don't really know what to do..... Thanks!
First, please use code tags when posting code samples. They make the code much easier to read. I've added them for you above.
Now, what kind of errors are you getting? Compile errors, run time exceptions, wrong behavior? On a quick scan, I see you defined your Car class with a capital C, but you've written the constructor with a lowercase c. The constructor name has to match the class name exactly, even the case. That mismatch will cause a compile error. If it still doesn't compile after you fix that, post the messages the compiler gives you and we'll try to figure it out together.
In addition to what Greg said, don't construct new Cars in the paintComponent(...) override. Painting methods are for painting, and painting alone. You have absolutely no control over how often or how many times that method will be called.
There are no new questions, but there may be new answers.

Thanks to both of you! You're more helpful than my programming professor.... It was the lower case letter in the car constructor which was causing the error. That was something that I just wouldn't have seen! Thank you both again!
