Why should fields in a Java class be declared private?

Focus: Encapsulation
Java: Encapsulation
Answer
To control access and protect the internal state.
Declaring fields as private ensures that only methods within the class can modify them, preserving the integrity of the class's state. For example, an `Order` class in an e-commerce system with a private `totalPrice` field can ensure that the total price is only calculated through its methods, preventing accidental or unauthorized changes.
