Implement Person Repository Class:

[davidshin0302]

Tasks:

• Implement Repository Class:

Create PersonRepositoryImpl in the repository package. Implement logic to read from and write to a JSON file using Jackson library methods. Ensure the repository handles edge cases like empty or malformed JSON files.

• Testing:

Write unit tests to verify the findAll(), findById(), save(), and deleteById() methods function as expected. Create sample data in persons.json to test with.

Acceptance Criteria:

A PersonRepositoryImpl class exists and correctly handles CRUD operations for Person objects via JSON file I/O. Methods should work as expected with test data. Unit tests should cover all repository methods.
