I know that there is already codes for numerous different inventory programs. I have read them, and I am still somewhat confused. OK, this is what my code is supposed to be doing: Modify the Inventory Program by creating a subclass of the product class that uses one additional unique feature of the product you chose (for the DVDs subclass, you could use movie title, for example). In the subclass, create a method to calculate the value of the inventory of a product with the same name as the method previously created for the product class. The subclass method should also add a 5% restocking fee to the value of the inventory of that product.
• Modify the output to display this additional feature you have chosen and the restocking fee.
This is the errors I keep getting: /tmp/27473/Product.java:10: class, interface, or enum expected

Finally, here is my codes:

I have been reading and rereading, but I just get more and more confused. When I think I do something right, I ask my teacher and he makes me feel like an idiot. Any help at all is greatly appreciated. Thanks!
Ok, I've been working on the code trying to get rid of some of the errors. I am down to one in my inventory.java file. This is the error: Inventory.java:26: illegal start of expression

Doesn't look like I've made much difference!
Here is the code once again:

Again, thanks for any help!
