This pull request resolves a compilation error in the Java Aggregation example.
🔧 Changes Made:
Added a getName() method in the Professor class to properly access the private name field.
Replaced direct field access (professor.name) in the University class with a call to professor.getName().
🐞 Issue Fixed:
In the original code, the showProfessors() method attempted to access professor.name, which is declared private in the Professor class. This violates encapsulation and causes a compilation error.
✅ Outcome:
The updated code now compiles and runs correctly, maintaining object-oriented principles by using proper encapsulation.
