Thread: Please Help stuck on Inheritances and abstract classes.

I am not asking you to do my homework. I am legitlly stuck on this and cannot figure out how to fix it. It seems that i cannot get the packages to see each other. Thanks for any Help.

Using Jgrasp

public abstract class Book
{
	private String title;
	private double price;
 
	public abstract void setPrice();
	public double getPrice()
        {
            return price;
        }
 
	public void setTitle(String bk_title)
        {
            title = bk_title;
        }
	public String getTitle()
        {
            return title;
        }
 
}

import Book.java;
 
public class Fiction extends Book
{
	Fiction fic = new Fiction();
	public void setPrice(double bk_price)
	{
		price = bk_price;
	}
 
	fic.getPrice()
	{
		return price;
	}
}

public class Nonfiction extends Book
{
Nonfiction nonfic = new Nonfiction();
nonfic.setPrice(double)
{
price = 37.99;
}
 
nonfic.getPrice()
{
return price;
}
}

import Book.java;
import Fiction.java;
import NonFiction.java;
 
public class UseBook {
public static void main(String[]args)
{
 
System.out.println("price for fiction: $" + price);
System.out.println("price for nonfiction: $" + bk_price);
}
}

Here are the errors:

UseBook.java:1: error: package Book does not exist
import Book.java;
