I Am Working On A Java Program That Implements Abstracts Classes And Such

“I am working on a Java program that implements abstracts, classes, and such. It is a simple racing program that takes all of what is learned, though I grasp the concept of abstracts, I don’t quite understand how to implement them. I would like help with the program, in a way that will help me be able to utilize it later, please do not just give an answer with out a good explanation. Even assistance with screen sharing would be helpful. “
