Java - Product Class

 

Given main(), define the Product class that will manage product inventory. Product class has three private member fields: a product code
(String), the product's price (double), and the number count of product in inventory (int).
Implement the following Constructor and member methods as listed below:
• public void addInventory(int amt) - increase inventory by parameter amt
• public void sellInventory(int amt) - decrease inventory by parameter amt
Ex. If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is:
Name: Apple
Price: 0.40
Count: 3
Ex. If 10 apples are added to the Product object's inventory, but then 5 are sold, the output is:
Name: Apple
Price: 0.40
Count: 8
Ex. If the Product object's code is set to "Golden Delicious", price is set to 0.55, and count is set to 4, the output is:
Name: Golden Delicious
Price: 0.55
Count: 4

• public Product(String code, double price, int count) - set the member fields using the three parameters
• public void setCode(String code) - set the product code (i.e. SKU234) to parameter code
• public String getCode() - return the product code
• public void set Price(double p) - set the price to parameter p
• public double getPrice() - return the price
