Given the following UML Class Diagram

Stock

-name: String

-Items: Arraylist

+ Stock (all parameters)

+ getName(): String

+ getItems (): ArrayList

+addElectronic(E: Electronic)

+addGrocery(G: Grocery)

+countElectronic(): int

+countGrocery(): int

StockItem

# brand: String

# price: double

# discount: double

+ StockItem(all parameters)

+ Setters & Getters

+ toString() : String

Grocery

- expiryYear : int

- weight: double

+ Grocery (all parameters)

+ Setters & Getters

+ toString(): String

Electronic

- type: String

- power: double

+ Electronic (all parameters)

+ Setters & Getters

+ toString(): String

[15 pts] Implement the class StockItem, which contains:

1. A constructor which accepts all required arguments
2. Set & get method for each data attribute.
3. A toString() method which returns a String containing all attributes of StockItem object as follows.

Assume the object is a Kenwood whose price is $230 and discount= 0.08. The toString() method returns: Kenwood ($230) has discount = 8%

Assume the object is a Kenwood whose price is $230 and discount= 0.0. The toString() method returns:

Kenwood ($230)

[15 pts] Implement the Grocery class as described in the class diagram.

1. A constructor which accepts all required arguments (5 parameters)
2. Set & get method for each data attribute.
3. A toString() method which returns a String containing all attributes of Grocery object as follows:

Nutella ($7.5) has discount = 10%, expiry Year = 2022 (0.75Kg)

Septol ($5) , expiry Year = 2025 (0.45Kg)

[15 pts] Implement the Electronic class as described in the class diagram.

1. A constructor which accepts all required arguments (5 parameters)
2. Set & get method for each data attribute.
3. A toString() method which returns a String containing all attributes of Electronics as follows:

Kenwood ($230) discount = 8% (in Home Appliances) 1800Watt

[15 pts] Implement the class Stock, which contains:

4. A constructor which accepts the name and create an array of stock items
5. The following methods:
   1. getName: returns the name of stock
   2. getItems: returns an array of stock Items
   3. addElectronic: to add an Electronic item to array
   4. addGrocery(G: Grocery): to add Grocery item to array
   5. countElectronic(): gives the number to electronic item
   6. countGrocery(): gives the number to Grocery item

Part II: Driver Class

Question I [40 points]

Write a test/driver program to:

1. [10 pts] Create a stock object named Kadisha.
2. [10 pts] Fill the stock with Grocery and Electronics items of your choice.
3. [10 pts] Print all expired Grocery items (that have an expiry date less than 2021).
4. [10 pts] Get the brands, type and price after discount of Electronics items having discount.
