Answer
Validation prevents invalid or harmful data from affecting the collection.
Validating inputs ensures that only appropriate data is allowed to modify internal collections, preserving the object's intended state. For example, in an e-commerce application, validating that a product's SKU is unique before adding it to a catalog prevents duplicate entries that could confuse order processing.
