Okay, here's a detailed breakdown of a "Smart Wedding Planning Assistant" project, focusing on its core components, logic, Java code examples (for key features), and considerations for real-world deployment.

**Project Title:** Smart Wedding Planning Assistant

**Project Goal:** To create a user-friendly application (primarily web-based) that streamlines wedding planning by providing budget tracking, vendor management, task automation, and communication tools.

**Target Users:** Couples planning their wedding, wedding planners (professional use).

**Core Features:**

1.  **Budget Management:**
    *   **Functionality:** Allows users to set a total budget, allocate funds to different categories (venue, catering, photography, etc.), track actual expenses, and visualize budget progress.
    *   **Logic:**  Stores budget categories and their allocated amounts.  Records each expense transaction with its category, date, vendor, and amount.  Calculates remaining budget in each category and overall.  Generates reports (charts, tables) to visualize spending.
    *   **Java Example (Simplified Expense Tracking):**

        ```java
        import java.util.ArrayList;
        import java.util.List;

        public class BudgetTracker {

            private double totalBudget;
            private List<Expense> expenses;

            public BudgetTracker(double totalBudget) {
                this.totalBudget = totalBudget;
                this.expenses = new ArrayList<>();
            }

            public void addExpense(Expense expense) {
                expenses.add(expense);
            }

            public double calculateRemainingBudget() {
                double totalSpent = expenses.stream().mapToDouble(Expense::getAmount).sum();
                return totalBudget - totalSpent;
            }

            public void printReport() {
                System.out.println("Total Budget: $" + totalBudget);
                System.out.println("Total Spent: $" + expenses.stream().mapToDouble(Expense::getAmount).sum());
                System.out.println("Remaining Budget: $" + calculateRemainingBudget());
            }

            //Getters and setters
            public double getTotalBudget() {
                return totalBudget;
            }

            public void setTotalBudget(double totalBudget) {
                this.totalBudget = totalBudget;
            }

            public List<Expense> getExpenses() {
                return expenses;
            }

            public void setExpenses(List<Expense> expenses) {
                this.expenses = expenses;
            }

            public static void main(String[] args) {
                BudgetTracker tracker = new BudgetTracker(10000.0);
                tracker.addExpense(new Expense("Venue", 5000.0, "Grand Ballroom", "01/01/2024"));
                tracker.addExpense(new Expense("Catering", 2000.0, "Delicious Catering", "01/02/2024"));
                tracker.printReport();
            }

        }

        class Expense {
            private String category;
            private double amount;
            private String vendor;
            private String date;

            public Expense(String category, double amount, String vendor, String date) {
                this.category = category;
                this.amount = amount;
                this.vendor = vendor;
                this.date = date;
            }

            //Getters and setters
            public String getCategory() {
