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

Solution
Sure, I can help with that. Here's a step-by-step guide to implement the inventory management system in Java:
- Create a new Java class named
InventorySystem.
public class InventorySystem {
}
- Declare the static variables inside the
InventorySystemclass.
public class InventorySystem {
static final int MAX_ITEMS = 10;
static String[] items = new String[MAX_ITEMS];
static int[] quantities = new int[MAX_ITEMS];
}
- Implement the
mainmethod inside theInventorySystemclass.
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
while (true) {
System.out.println("1. Add item to inventory\n2. Sell item from inventory\n3. Display inventory\n4. Exit");
int choice = scanner.nextInt();
switch (choice) {
case 1:
addItem(scanner);
break;
case 2:
sellItem(scanner);
break;
case 3:
displayInventory();
break;
case 4:
System.exit(0);
}
}
}
- Implement the
displayInventorymethod.
public static void displayInventory() {
for (int i = 0; i < MAX_ITEMS; i++) {
if (items[i] != null) {
System.out.println("Item: " + items[i] + ", Quantity: " + quantities[i]);
}
}
}
- Implement the
addItemmethod.
public static void addItem(Scanner scanner) {
System.out.println("Enter item name:");
String item = scanner.next();
for (int i = 0; i < MAX_ITEMS; i++) {
if (items[i] != null && items[i].equals(item)) {
System.out.println("Enter quantity to add:");
int quantity = scanner.nextInt();
quantities[i] += quantity;
return;
}
}
for (int i = 0; i < MAX_ITEMS; i++) {
if (items[i] == null) {
items[i] = item;
quantities[i] = 1;
return;
}
}
}
- Implement the
sellItemmethod.
public static void sellItem(Scanner scanner) {
System.out.println("Enter item name:");
String item = scanner.next();
for (int i = 0; i < MAX_ITEMS; i++) {
if (items[i] != null && items[i].equals(item)) {
if (quantities[i] > 0) {
System.out.println("Enter quantity to sell:");
int quantity = scanner.nextInt();
quantities[i] -= quantity;
} else {
System.out.println("Item is out of stock.");
}
return;
}
}
System.out.println("Item not found.");
}

An Inventory Management System for a retail store that sells various products. The system allows the store to keep track of its inventory, manage stock levels, and analyze inventory statistics. The retail store can use this Inventory Management System to maintain an organized record of its products. Store managers can input new inventory items, update existing item details, and analyze inventory statistics. The system helps in making informed decisions regarding stock replenishment, pricing strategies, and product promotions. The Inventory Management System is going to perform four operations initially that is Inventory Tracking, Displaying Inventory Details, Inventory Analysis, and Reporting. In an Inventory tracking option, the user inputs the number of items to be tracked in the inventory. For each item, the user inputs details such as name, quantity, price, and category. The system stores this information in an array of structures representing inventory items. After the user inputs all the inventory details, the system displays the details of each item entered. The details include the name, quantity, price, and category of each item. Inventory Analysis, the system includes functions to calculate the total stock value and find the most expensive item in the inventory. The total stock value is calculated by multiplying the quantity of each item by its price and summing up these values. The most expensive item is determined by comparing the prices of all items and identifying the one with the highest price. Once the inventory details are displayed, the system generates a report with the following information, Total stock value: The sum of the values of all items in the inventory. Most expensive item: The name of the item with the highest price. Inventory Management System Input the number of items to be tracked in the inventory Name Quantity Price Category Display the details of each item in the inventory Name Quantity Price Category Calculate and display the total stock value Find and display the most expensive item Sample input: 3 Laptop 20 50000 Electronics Jeans 50 1000 Apparel Headphones 60 900 Accessories Sample output Laptop 20 50000.00 Electronics Jeans 50 1000.00 Apparel Headphones 60 900.00 Accessories 1104000.00 Laptop code in c language

You are tasked with managing an inventory of products in a retail store. The inventory contains various products, each with a name(key) and price(value). Use dictionary to create the inventory. Write a Python program to find the total value of products that strictly exceed a certain threshold value. Further, display the name of products whose price is less than or equal to the threshold value (Each product name should be printed in a separate line). Develop code by using user-defined function whose argument is a dictionary. DO NOT USE BUILT-IN FUNCTIONS IN CALCULATING THE RESULTS.Accept the number of products in the inventory from user, say N.Read product name and value from user for N number of products.Read threshold value from user.Print the total value of products above threshold.
