Overview This project will progress with you throughout the course. After each section there will be more to add unti it builds into requirements are met. Include all parts in a package called javainventory to maintain Inventory. For each part, build upon the last part so that both the old and new that can be used for a range of products (ods, dvds, software, etc.) Requirements- (Solutions: ProductParts, ProductTesterParts At this point, students should create new classes functionality of the project (copy and paste part 4 code into new part 5 classes ProductParts and ProductTesterPart5 that will add onto the Topic(s): Adding a subclass, using extends, using superO, overriding methods from a superclass. Create a subclass of the ProductParts class that has two additional variables. (For example, a DVD subclass could use movie title and length). 1. In the subclass, override the method to calculate the value of the inventory of a product with the same name as that method previously created for the product dass. The subclass method should also add a 5% restocking fee to the value of the inventory of that product. 2. 3 can be printed to the output. Display the subclass products using a for loop.
