Java: Controlled Mutation
Answer
It prevents unintended changes to object state.
Immutability means an object's state cannot change after it's created. This is useful for ensuring consistency and preventing errors due to unexpected changes. For instance, an `Order` object with immutable fields like `orderId` and `date` ensures these critical details remain consistent throughout its lifecycle in an e-commerce system.
