| The elements of this class are STORED in a dynamic array. This class now supports the storage of all types of objects thanks to the addition of generics. | The elements of this class are stored in a doubly-linked list. This class, like the ArrayList, allows for the storage of any type of object. |
| The List interface is implemented by this class. As a result, this SERVES as a list. | The List and Deque interfaces are both implemented by this class. As a result, it can be used as both a list and a deque. |
| Because of the internal implementation, manipulating an ArrayList takes LONGER. Internally, the array is scanned and the memory bits are shifted whenever we remove an element. | Because there is no concept of changing memory bits in a doubly-linked list, manipulating it takes less time than manipulating an ArrayList. The reference link is changed after traversing the list. |
| This class is more useful when the application requires DATA storage and access. | This class is more useful when the application requires data manipulation. |
