✨ Features

Patient Management

• ✅ CRUD Operations: Add, view, update, and archive patient records
• 📂 Archival System: Safely archive/unarchive records without deletion
• 🔍 Search: Find patients by ID
• 📝 Detailed Records:
  • Personal info, medical history, allergies, treatment plans
  • Emergency contacts, assigned doctors

Doctor Management

• 👨‍⚕️ Add/View Doctors: Track doctor specializations
• 🏷️ Assign Doctors: Link patients to doctors

User Experience

• 🎨 Color-Coded Console: ANSI colors for better readability
• ✔️ Input Validation: Ensures correct formats (dates, phone numbers, etc.)
• 📅 Auto Age Calculation: From date of birth

Security & Compliance

• 🔒 Privacy Notice: Prompts users about data confidentiality
• ♻️ Safe Archiving: Prevents accidental data loss

🛠️ Technical Implementation

OOP Principles Used

• Encapsulation: Private fields with getters/setters
• Abstraction: Separate UI (*View classes) from logic (*Service classes)
• Composition: PatientService depends on DoctorService

Key Classes

Class	Purpose
Patient	Stores patient data (ID, name, medical history, etc.)
Doctor	Manages doctor details (ID, name, specialization)
PatientService	Handles patient operations (CRUD, archiving)
InputValidator	Validates user inputs (numbers, dates, text)
MenuUtil	Manages console UI (menus, screen clearing)

Error Handling

• Try-catch blocks with colored error messages
• Prevents crashes on invalid inputs
