Sample Code

import java.util.HashMap;
import java.util.Map;

// Class representing an item in the warehouse
class Item {
    String id;
    String name;
    double price;

    public Item(String id, String name, double price) {
        this.id = id;
        this.name = name;
        this.price = price;
    }

    // Getters and setters not shown for brevity
}

// Main Warehouse Management System class
public class WarehouseManagementSystem {
    // Inventory map to hold items and quantities
    private Map<Item, Integer> inventory;

    public WarehouseManagementSystem() {
        this.inventory = new HashMap<>();
    }

    // Add items to the inventory
    public void addItem(Item item, int quantity) {
        inventory.put(item, inventory.getOrDefault(item, 0) + quantity);
    }

    // Remove items from the inventory
    public boolean removeItem(Item item, int quantity) {
        if (!inventory.containsKey(item) || inventory.get(item) < quantity) {
            System.out.println("Not enough inventory or item does not exist.");
            return false;
        }
        inventory.put(item, inventory.get(item) - quantity);
        return true;
    }

    // Display inventory
    public void displayInventory() {
        System.out.println("Inventory:");
        for (Map.Entry<Item, Integer> entry : inventory.entrySet()) {
            Item item = entry.getKey();
            Integer quantity = entry.getValue();
            System.out.println("Item ID: " + item.id + ", Name: " + item.name + ", Quantity: " + quantity);
        }
    }

    // Main method for demonstration
    public static void main(String[] args) {
        WarehouseManagementSystem wms = new WarehouseManagementSystem();

        // Adding some items
        wms.addItem(new Item("1", "Widget", 19.99), 150);
        wms.addItem(new Item("2", "Gadget", 29.99), 90);

        // Displaying current inventory
        wms.displayInventory();

        // Removing some items
        wms.removeItem(new Item("1", "Widget", 19.99), 50);

        // Displaying inventory after removal
        wms.displayInventory();
    }
}
