"Cannot Find Symbol" Why?

So I am writing code for a programming class that simulates a website where customers can buy Products and add them to a Cart. I have made a Product and Cart class. They are both in the some directory and their .class files are in the same package. So why am I getting "cannot find symbol" on Product when compiling my Cart class? Help plz! and ty

Cart class:

package com.DownloadThis; import java.util.ArrayList; public class Cart { private ArrayList<Product> myCart; public Cart() { myCart = new ArrayList<Product>(); } public void addProduct(Product p) { myCart.add(p); } public float getTotal() { float totalPrice = 0; for(int i = 0; i < myCart.size(); i++) { Object obj = myCart.get(i); Product p = (Product)obj; totalPrice = totalPrice + p.getPrice(); } return totalPrice; } public void addToCart(int product_id) { } } 

Product class:

package com.DownloadThis; import java.sql.*; public class Product { private String artist; private String album; private int year; private String genre; private float price; private String albumart; private String username; private String password; private Connection connection = null; private ResultSet rs = null; private Statement st = null; public Product() { } public Product(String artist, String album, int year, String genre, float price, String albumart) { this.artist = artist; this.album = album; this.year = year; this.genre = genre; this.price = price; this.albumart = albumart; } public String getArtist() { return this.artist; } public void setArtist(String artist) { this.artist = artist; } public String getAlbum() { return this.album; } public void setAlbum(String album) { this.album = album; } public int getYear() { return this.year; } public void setYear(int year) { this.year = year; } public String getGenre() { return this.genre; } public void setGenre(String genre) { this.genre = genre; } public float getPrice() { return this.price; } public void setPrice(float price) { this.price = price; } public String getAlbumart() { return this.albumart; } public void setFilename(String albumart) { this.albumart = albumart; }
