I created a controller, CalendarBreakController.java, that contains API endpoints to receive requests from frontend (calendar.md) regarding the creating, displaying, editing, and deleting of breaks. I also created three files, CalendarBreak.java, CalendarBreakRepository.java, and CalendarBreakService.java, which create the database for saving breaks from frontend.

API Endpoints Created/Enhanced:

1. POST /api/calendar/breaks/create (FIXED & ENHANCED)

• Validates that name is not empty
• Implements next-non-break-day logic
• Returns complete break object with all fields

2. PUT /api/calendar/breaks/{id} (NEW)

• Edit break name and description
• Proper error handling for non-existent breaks
• Returns updated break object

3. DELETE /api/calendar/breaks/{id} (ENHANCED)

• Cleaner path structure
• Proper success/error messages
• Events stay on their current dates (no automatic reversal)

4. GET /api/calendar/breaks/ (VERIFIED)

• Returns all breaks with name and description fields
• Properly populated responses

5. GET /api/calendar/breaks/by-date (VERIFIED)

• Retrieves breaks for a specific date
• Works with the new fields

6. GET /api/calendar/breaks/is-break-day (VERIFIED)

• Checks if a date is a break day
• Returns boolean response

7. GET /api/calendar/breaks/{id} (VERIFIED)

• Retrieves specific break by ID

Key Technical Changes:

CalendarBreak.java - Updated entity with [name] fields

CalendarBreakService.java - Enhanced with: findNextNonBreakDay() method for calculating next available date
, and [updateBreak()] method for editing breaks

CalendarBreakController.java - Completely redesigned with new base path [/api/calendar/breaks] to avoid conflicts
, proper input validation
, comprehensive error handling
, all 7 endpoints with clean architecture

Database Schema - Updated calendar_breaks table with [name] columns

Testing Results:
All endpoints have been tested and verified working:

✓ Create breaks with custom names and descriptions
✓ Edit breaks
✓ Delete breaks
✓ Retrieve all breaks
✓ Retrieve breaks by date
✓ Check if date is a break day
✓ Proper error handling with appropriate HTTP status codes
