    Default 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.

    package auto;
     
    /* Auto class, Version 2
     Anderson, Franceschi
     */
    public class Auto
    {
    	// instance variables
    	private String model;	//  model of auto
    	private int milesDriven;	//  number of miles driven
    	private double gallonsOfGas; //  number of gallons of gas
     
    	// Default constructor:
    	//  initializes model to "unknown";
    	//  milesDriven is autoinitialized to 0
    	//        and gallonsOfGas to 0.0
    	public Auto( )
    	{
            model = "unknown";
    	}
     
    	// Overloaded constructor:
    	// allows client to set beginning values for
    	//   model, milesDriven, and gallonsOfGas.
    	public Auto( String startModel,
    	int startMilesDriven,
    	double startGallonsOfGas )
    	{
            model = startModel;
     
    	// validate startMilesDriven parameter
    	if ( startMilesDriven >= 0 )
               milesDriven = startMilesDriven;
    	else
    	{
    	System.err.println( "Miles driven is negative." );
    	System.err.println( "Value set to 0." );
    	}
     
    	// validate startGallonsOfGas parameter
    	if ( startGallonsOfGas >= 0.0 )
               gallonsOfGas = startGallonsOfGas;
    	else
    	{
    	System.err.println( "Gallons of gas is negative" );
    	System.err.println( "Value set to 0.0." );
    	}
    	}
     
    	// Accessor method:
    	// returns current value of model
    	public String getModel( )
    	{
    	return model;
    	}
     
    	// Accessor method:
    	// returns current value of milesDriven
    	public int getMilesDriven( )
    	{
    	return milesDriven;
    	}
     
    	// Accessor method:
    	//  returns current value of gallonsOfGas
    	public double getGallonsOfGas( )
    	{
    	return gallonsOfGas;
    	}

    Post the exact error message, copied and pasted from what appears at your end. What's the name of the source file?

    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
