Java: Invariants and Validation
Answer
Immutability ensures the object's state cannot change after creation.
Immutability prevents changes to an object's state, which is crucial for maintaining invariants. Once set, the object's state remains consistent and valid. For example, an immutable Product class could have a final price field that is set through the constructor, ensuring the price never changes and always stays valid.
