Problem StatementImplement a product inventory system for an e-commerce application. Your task is to create a Product class to represent individual products. The Product class should include the following attributes: id (integer): A unique identifier for each product.name (string): The name of the product.price (double): The price of the product.quantity (integer): The quantity available in stock.Your goal is to overload the = operator to enable the assignment of one Product object to another. When you assign one Product to another, it should copy all the attributes, creating a deep copy of the object.Input format :The first line of input consists of an integer representing the product ID.The second line of input consists of a string representing the product name.The third line of input consists of a double value representing the product price.The fourth line of input consists of an integer value representing the product quantity.Output format :The program displays the following information:The details of the original product(Product 1 details), including ID, name, price, and quantity in separate lines.The details of the copied product (Product 2 details), including ID, name, price, and quantity in separate lines.Refer to the sample outputs for the formatting specifications.Code constraints :Price is printed as such without any specific precisions.Sample test cases :Input 1 :1Widget A10.9950Output 1 :Product 1 details:ID: 1Name: Widget APrice: $10.99Quantity: 50Product 2 details (copy):ID: 1Name: Widget APrice: $10.99Quantity: 50Input 2 :102Dell253.65Output 2 :Product 1 details:ID: 102Name: DellPrice: $253.6Quantity: 5Product 2 details (copy):ID: 102Name: DellPrice: $253.6Quantity: 5

Observe the below class and match the output for the code snippets provided.public class Product{    //Attributes    private int productId;    private String productName;    private float price;    private char category;     //Constructor public Product(){ } public Product(int productId,String productName,float price) {     this.productId=productId;     this.productName=productName;     this.price=price; } public Product(int productId,String productName,float price,char category) { this(productId,productName,price); this.category=category;      } public void display()  { System.out.println(productId+"  "+productName+" "+price+" "+category); }    }Product p = new Product()p.display();Answer 1Product p = new Product(71,"Mobile",80000,'A');p.display();Answer 2Product p = new Product(501,"Wallet",520);p.display();Answer 3

Problem StatementIn an electronics store, to manage the inventory of electronic products. The system maintains a table named "Products" containing information about various electronic devices, including their ProductID, ProductName, and Price.To handle dynamic pricing updates, you are tasked with creating a stored procedure named 'UpdateProductPrice'. This procedure takes two parameters: p_ProductID (the ID of the product to be updated) and p_NewPrice (the new price to be set for the product).The following table is already created, and the records are inserted into the table.TABLE: Products ProductID INT PRIMARY KEY, ProductName VARCHAR(50), Price DECIMAL(10, 2).Prepopulated Records:Input format :The input records are already prepopulated, as given in the problem statement.Output format :The stored procedure updates the price of the specified product in the "Products" table.The output should display the updated product details as shown below.

Emily manages the stock for a small bookstore and receives a new shipment of books. She needs to update the current inventory by adding the quantities from the incoming shipment. Given the number of different book types and their quantities in both the current and incoming inventories, help Emily update the current inventory.Input format :The first line of input consists of an integer n, representing the number of book types.The second line consists of n space-separated integers, representing the current inventory.The third line consists of n space-separated integers, representing the incoming inventory.Output format :The output prints the updated inventory for each book type.Refer to the sample output for formatting specifications.Code constraints :1 ≤ n ≤ 20Sample test cases :Input 1 :315 20 2530 15 10Output 1 :45 35 35 Input 2 :250 1025 75Output 2 :75 85

Objective: The objective of this activity is to implement a basic inventory management system using Java programming concepts such as user-defined methods, scanner, arrays, loops, and conditions.Task Overview:1. Create a new Java class named `InventorySystem`.2. Declare the following static variables inside the `InventorySystem` class:   - `MAX_ITEMS`: an integer constant to define the maximum number of items in the inventory (set it to 10).   - `items`: a string array to store the names of the items in the inventory (initialize it with the size of `MAX_ITEMS`).   - `quantities`: an integer array to store the quantities of the items in the inventory (initialize it with the size of `MAX_ITEMS`).3. Implement the `main` method inside the `InventorySystem` class:   - Create a `Scanner` object named `scanner` to read user input from the console.   - Use a `while` loop to keep the program running until the user chooses to exit.   - Inside the loop, display a menu of options to the user:     1. Add item to inventory     2. Sell item from inventory     3. Display inventory     4. Exit   - Use a `switch` statement to execute the corresponding action based on the user's choice (1, 2, 3, or 4).   - If the user selects option 1, call the `addItem` method.   - If the user selects option 2, call the `sellItem` method.   - If the user selects option 3, call the `displayInventory` method.   - If the user selects option 4, exit the program.Sample Output 4. Implement the `displayInventory` method:   - Iterate through the `items` and `quantities` arrays and display the name and quantity of each item in the inventory.Sample OutputNote: For other displayInventory functions, check the sample output in the addItem and in the sellItem methods. 5. Implement the `addItem` method:   - Prompt the user to enter the name of the item to be added.   - Check if the item already exists in the inventory by searching for its name in the `items` array.   - If the item does not exist, add it to the list. Automatically it will have value of 1.   - If the item already exists, prompt the user to enter the quantity to be added.   - Update the quantity of the existing item in the `quantities` array.Sample Output6. Implement the `sellItem` method:   - Prompt the user to enter the name of the item to be sold.   - Check if the item exists in the inventory by searching for its name in the `items` array.   - If the item does not exist or if its quantity is 0, display an error message.   - If the item exists and its quantity is greater than 0, prompt the user to enter the quantity to be sold.   - Update the quantity of the sold item in the `quantities` array.Sample Output7. Compile and run the `InventorySystem` class to test the inventory management system.8. Test the system by adding items to the inventory, selling items, and displaying the current inventory.9. When exit is chosen, the program will terminate
