Answer
The build() method ensures that the constructed object is in a valid state before creation.
Before creating an immutable `Order` object, the build() method checks that all required fields are set and valid. If any mandatory fields such as order ID or customer details are missing, the build() method can throw an exception, preventing the creation of an invalid object.
