Java: List Interface and ArrayList
Answer
Lists must maintain insertion order and rely on equals() for equality.
The List interface guarantees that elements maintain their insertion order and checks element equality using the equals() method. This is crucial for operations like remove() or contains(), which depend on correctly overriding equals() in custom objects.
