The Array and ArrayList classes differ on the following features:
- Arrays can contain primitive or objects, while an ArrayList can contain only objects.
- Arrays have fixed size, while an ArrayList is dynamic.
- An ArrayList provides more methods and features, such as addAll, removeAll, iterator, etc.
- For a list of primitive data types, the collections use autoboxing to reduce the coding effort. However, this approach makes them slower when working on fixed size primitive data types.
