Inventory3 Creating a subclass of the product class that uses…

• 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 an example of what the print out is to look like. The only thing I cannot get is the restocking fee (5%): to calculate what it is. I have attached the program. Help please. The program will compile. I am using office supplies instead of DVD Movies.

Hi

I forgot to mention that I need the assignment for today by 12:00.

Jacob I compiled the program and it did not compile. There are two errors one on in line77 and line 109.

Hi Jacob

The program is still not compiling. Below are the three errors that came up.

C:\Users\Owner\Documents\Inventory2.java103: <identifier> expected

public double double CalculationInventoryValue ()

^

C:\Users\Owner\Documents\Inventory2.java103: invalid method declaration; return type required

public double double CalculationInventoryValue ()

Jacob

This is an example of what the output should look like after if compiles.

You helped with a different program that I needed help with and I really liked the work you gave me. Can you help me with another program that I have?
