Thread: Writing a class - class not found

I am studying defining a class in Java Programming.

I am having an issue with whenever I try to write a class, even one directly from the book, NetBeans tells me it can't find the class.

The code looks correct but it won't run. i don't understand what I am doing wrong.

public class Auto
{

	private String model;	//  model of auto
	private int milesDriven;	//  number of miles driven

I figured out what i had to do. it has to be a file all until itself within the program. I got confused. now it works correctly

Okay. Good job figuring it out.
