Answer
Private fields prevent external modification and maintain object integrity.
Private fields encapsulate the data within a class, preventing unauthorized access or changes from outside the class. This ensures that the object maintains its intended state. For instance, in an e-commerce system, making `price` a private field in a `Product` class prevents accidental changes to the price from external code, which could otherwise lead to inconsistency or errors.
