Java: Fail Fast Validation
Answer
Fail-fast validation is the practice of immediately rejecting invalid input.
Fail-fast validation ensures that invalid data is rejected as soon as it is detected, preventing it from propagating through the system. For example, in a checkout system, if a user enters a negative quantity for an item, the system should immediately throw an IllegalArgumentException instead of proceeding with the order processing.
