Track: Java
Topic: OOP
Focus: Fields and State
Java: Fields and State
Answer
Making fields public can expose internal state, leading to data integrity issues.
Public fields allow unrestricted access, potentially leading to invalid states. For example, if a Product class has a public 'price' field, any part of the program can change it without validation, risking incorrect pricing.
