Block 1: Main Class
```java
public class FurnitureStoreManagement {
public static void main(String[] args) {
// Main menu class installation
Menu menu = new Menu();
// display the menu
menu.display();
}
}
```
This is the entry point of the program. It creates an instance of the `Menu` class and invokes its `display` method to start the application. The `Menu` class is responsible for managing the menu-driven interaction.
Block 2: Menu Class
```java
class Menu {
public void display() {
// ...
}
}
```
The `Menu` class defines the menu-driven interface. It initializes instances of `Inventory`, `StockAllocation`, and `ReportGenerator`, and then enters a loop that displays a menu to the user. Depending on the user's choice, it performs various operations like adding, removing, and updating stock items, allocating stock to an order, and generating reports.
Block 3: ReportGenerator Class
```java
class ReportGenerator {
public void generateInventoryReport(Inventory inventory) {
System.out.println("....::: Inventory Report :::....");
System.out.println("Item ID\t\tQuantity\t\tPrice");
for (String itemId : inventory.getStockItems().keySet()) {
System.out.println(itemId + "\t\t\t" + inventory.getItemQuantity(itemId) +
"\t\t\t\t" + inventory.getStockItems().get(itemId).getPrice());
}
System.out.println("____________________________________________");
}
public void generateAllocationReport(StockAllocation stockAllocation) {
System.out.println("....::: Allocation Report :::....");
System.out.println("Item ID\t\tAllocated Quantity");
for (String itemId : stockAllocation.getAllocatedStock().keySet()) {
System.out.println(itemId + "\t\t\t" + stockAllocation.getAllocatedStock().get(itemId).getQuantity());
}
System.out.println("____________________________________________");
}
}
```
The `ReportGenerator` class is responsible for generating inventory and stock allocation reports. It contains methods to create reports based on the data provided as arguments.
Block 4: StockAllocation Class
```java
import java.util.HashMap;
import java.util.Map;
class StockAllocation {
private Map allocatedStock;
public StockAllocation() {
this.allocatedStock = new HashMap<>();
}
// Allocate stock to an order
public void allocateStock(String itemId, int quantity, Inventory inventory) {
// Check if the item is in the inventory and has enough stock
if (!inventory.itemExists(itemId)) {
System.out.println("Error: Item not found in inventory.");
System.out.println("____________________________________________");
return;
}
int currentQuantity = inventory.getItemQuantity(itemId);
if (currentQuantity < quantity) {
System.out.println("Error: Not enough stock available.");
System.println("____________________________________________");
return;
}
// Allocate stock and update inventory
int updatedQuantity = currentQuantity - quantity;
inventory.updateItemQuantity(itemId, updatedQuantity);
StockItem newItem = new StockItem(itemId, inventory.getStockItems().get(itemId).getItemName(),
quantity, inventory.getStockItems().get(itemId).getPrice());
allocatedStock.put(String.valueOf(allocatedStock.size() + 1), newItem);
System.out.println("Stock allocated successfully. Updated quantity: " + updatedQuantity);
System.out.println("____________________________________________");
}
public Map getAllocatedStock() {
return allocatedStock;
}
}
```
The `StockAllocation` class handles the allocation of stock to orders. It maintains a map of allocated stock items and provides a method to allocate stock to an order. The `allocateStock` method checks if the item exists in the inventory and has sufficient quantity.
Block 5: StockItem Class
```java
class StockItem {
// ...
}
```
The `StockItem` class represents individual stock items and contains fields for item ID, name, quantity, and price. It also includes getter and setter methods for these fields.
Block 6: Inventory Class
```java
import java.util.HashMap;
import java.util.Map;
class Inventory {
private Map stockItems;
public Inventory() {
this.stockItems = new HashMap<>();
}
// Add a new stock item to the inventory
public void addNewItem(StockItem newItem) {
stockItems.put(newItem.getItemId(), newItem);
}
// Remove a stock item from the inventory
public void removeItem(String itemId) {
stockItems.remove(itemId);
}
// Update the quantity of a stock item
public void updateItemQuantity(String itemId, int newQuantity) {
StockItem item = stockItems.get(itemId);
if (item != null) {
// Update the quantity of the item
item.setQuantity(newQuantity);
}
}
public boolean itemExists(String itemId) {
return stockItems.containsKey(itemId);
}
public int getItemQuantity(String itemId) {
if (itemExists(itemId)) {
return stockItems.get(itemId).getQuantity();
} else {
System.out.println("Error: Item not found in inventory.");
return -1;
}
}
public Map getStockItems() {
return stockItems;
}
}
```
The `Inventory` class manages the inventory of stock items. It maintains a map of stock items and provides methods for adding, removing, and updating stock items, as well as checking if an item exists and retrieving item quantities.
