Answer» Array and Collection are equivalent in terms of STORING object references and manipulating data, but they differ in a number of ways. The following are the primary distinctions between an array and a Collection: | Array | Collection |
|---|
| Arrays have a SET size, which means that once we build one, we can't change it to meet our needs. | Collection are naturally grow-able and can be customized to meet our needs. We can change its size as per our requirement. | | When it comes to performance, Arrays are the preferred to Collection. | Considering performance, Collection are not preferred to Arrays. | | Only homogeneous data type elements can be stored in arrays. | Both homogeneous and heterogeneous components can be stored in a collection. | | Because arrays have no underlying data STRUCTURE, there is no ready-made METHOD support. | Any collection class is built on a standard data structure, and so there is ready-made method support for every demand as a performance. These methods can be used directly, and we are not RESPONSIBLE for their implementation. | | Objects and primitives can both be stored in arrays. | Only object types can be stored in a collection. | | When it comes to memory, Arrays are not preferred to Collection. | Considering memory, Collection are preferred to Arrays. |
