Title: Smart Task Scheduler with Priority-Based Execution

Problem Statement: Students and professionals often struggle to manage multiple deadlines with varying levels of urgency and complexity. Most existing to-do applications rely on manual prioritization and do not dynamically adjust task order when deadlines or workload conditions change. This leads to inefficient planning and missed commitments. The proposed Smart Task Scheduler aims to address this limitation by modeling tasks through a structured object-oriented hierarchy. Each task will encapsulate attributes such as priority, deadline, and estimated duration. A priority queue–based scheduling mechanism will automatically reorder tasks as conditions evolve, demonstrating clear abstraction, modularity, and extensible system design.

Target User: College students and early-career professionals managing academic or project deadlines.

Core Features:

• Add, update, and delete tasks
• Priority-based dynamic ordering
• Recurring vs one-time task handling
• Automatic deadline re-evaluation
• Persistent storage
• Robust exception handling

OOP Concepts to be Used:

• Abstraction: Abstract Task class defining shared behavior
• Inheritance: Specialized subclasses for task types
• Polymorphism: Overridden priority evaluation logic
• Exception Handling: Invalid input and deadline conflict handling
• Collections: PriorityQueue for dynamic ordering

Architecture: The system follows a layered object-oriented architecture where an abstract Task class defines common behavior, and specialized subclasses implement specific task types. A central SchedulerManager coordinates task prioritization and execution logic, while a separate persistence layer handles storage and retrieval, ensuring clear separation of concerns between domain logic and data management.
Abstract Task class → Specialized subclasses → Scheduler Manager → Persistence layer.
