Question

Beggning of java

Use inheritance with the Product application

modify the Product application so it provides for an additional kind of product: a music album. When you enter the code for a music album, it should look like this:

Enter product code sgtp
Description Sgt. Peppers(The Beatles)
Price $14.99 Product count 1

Create a new subclass named Album

I. Import the project named ch 11-ex l-Product that's in the ex-starts folder. Then, review the code.
2. In the murach business package, create a new class named Album that inherits the Product class. This new class should store data about the artist of the album. In addition, its toString method should append the name of the artist to the end of the string
Modify the ProductDB class so it returns an Album object
3. Modify the ProductDB class so it creates at least one Album object.
4. Run the application to make sure that it works correctly.

Modify the protected variable
5, open the Product class and delete the protected access modifier for the count variable. This restricts the availability of this variable even further, making it only available to the other classes in the current package.
6 Run the application to make sure that the count is maintained properly.

I want the code for this the product application code please
