Answer
By returning a copy or an unmodifiable view.
To prevent external modification of a private list, you can return a copy or an unmodifiable view of the list. This ensures that the original list remains unchanged, preserving the object's integrity. For instance, a Store class might keep its list of orders private but provide a method that returns an unmodifiable list to external callers.
