Please provide the whole CODE of my qustion base on the Below codes

Part 1 code :

import java.util.Scanner;

public class ItemInStock {

private String itemCode;

private String itemName;

private String itemDescription;

private int quantity;

private double itemPrice;

private String item_category;

public ItemInStock(String itemCode, int quantity, double itemPrice) {

this.itemCode = itemCode;

this.quantity = quantity;

this.itemPrice = itemPrice;

}

public String getItemCode() {

return this.itemCode;

}

public void setItemCode(String itemCode) {

this.itemCode = itemCode;

}

public String getItemName() {

return this.itemName;

}

public void setItemName(String itemName) {

this.itemName = itemName;

}

public String getItemDescription() {

return this.itemDescription;

}

public void setItemDescription(String itemDescription) {

this.itemDescription = itemDescription;

}

public int getQuantity() {

return this.quantity;

}

public void setQuantity(int quantity) {

this.quantity = quantity;

}

public double getItemPrice() {

return this.itemPrice;

}

public void setItemPrice(double itemPrice) {

this.itemPrice = itemPrice;

}

public String getItem_category() {

return item_category ;

}

public void setItem_category(String item_category) {

this.item_category = item_category;

}

public void addItem() {

if (this.quantity + 1 > 25) {

System.out.println("The error: Item stock must not exceed 25 items");

} else {

this.quantity++;

}

}

public void itemSell() {

Scanner scanner = new Scanner(System.in);

System.out.print("Enter the quantity of items to sell: ");

int sellQuantity = scanner.nextInt();

if (sellQuantity > this.quantity) {

System.out.println("Error: Not enough items in stock");

} else {

this.quantity -= sellQuantity;

}

}

public double taxOnItem() {

return this.itemPrice * 0.05;

}

public double getItemPriceWithTax() {

return this.itemPrice + this.taxOnItem();

}

public void getItemDetails() {

System.out.println("Item Category: " + this.getItem_category());

System.out.println("Item Name: " + this.getItemName());

System.out.println("Description: " + this.getItemDescription());

System.out.println("StockCode: " + this.getItemCode());

System.out.println("Price Without Tax: R. O " + this.getItemPrice());

System.out.println("Price With Tax: R.O " + this.getItemPriceWithTax());

System.out.println("Total quantity in store: " + this.getQuantity());

}

}

Part 2 code

public class HP_Laptop extends ItemInStock {

private String processor;

private int memory;

private int storage;

public HP_Laptop(String itemCode, int quantity, double itemPrice, String processor, int memory, int storage) {

super(itemCode, quantity, itemPrice);

this.processor = processor;

this.memory = memory;

this.storage = storage;

}

@Override

public String getItem_category() {

return "Laptop";

}

@Override

public String getItemName() {

return "HP Laptop";

}

@Override

public String getItemDescription() {

return "HP " + processor + " " + memory + "GB " + storage + "GB";

}

@Override

public void getItemDetails() {

super.getItemDetails();

System.out.println("Processor: " + processor);

System.out.println("Memory: " + memory + "GB");

System.out.println("Storage: " + storage + "GB");

}

}

HeRe is the qustion

In this and final part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods.

You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism.

Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method.

You should be creative and come up with your own ideas of sub-classes.

Task 3.1. Draw a UML class diagram with all the classes and relationships.

Task 3.2. Write code in Java with all these classes implementation and a program called Polymorphism_works with member method specific_Item which takes one instance of Item_in_Stock class as a parameter. Perform functionality of adding items, selling items and changing item price and displaying items details against specific item instance. There should be a main () method which declares an array of objects containing instance of sub classes of Item_in_Stock class and then calls methods of each of the implemented classes

In pic it is the example how it can be start and I am beging you write the whole code for me with all 3 subclass and abstract and use the things asked in qustion plsplsplspla

PLS PLS PLS write the code complitly base on part 1 and 2 code, If I got the answer I will give upvote and good feedback

Example. class polymorphism_works \{ public static void specific_Item(Item_in_Stock OBJ)\{ System.out.println("Item in stock details"); System.out.println(OBJ); 3 public static void main(String] args) \{ Item_in_Stock [] Item_list = new Item_in_Stock [3]
