Java: Fail Fast Validation
Answer
It ensures objects are initialized in a valid state.
Fail-fast validation in constructors confirms that an object is properly initialized when it is created, preventing future errors due to invalid states. For instance, if a `Customer` object requires a non-null email, checking this in the constructor ensures the object is always usable.
