the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > yes, collection(e.g., a List, Dictionary, HashSet, etc.) that can hold different types of data, Arrays can only hold the same type of data.
This is because collections and arrays are implemented differently internally. An array is a contiguous piece of storage in memory for elements of the same type. Thus, once an array is created, its length and element type are fixed and cannot be changed at run time.
Whereas a collection is a data structure consisting of one or more objects, elements can be dynamically added or removed at run time. The data structure used inside the collection is not necessarily continuous storage space, can use a variety of data structures, such as linked lists, hash tables, so that different types of data can be loaded.
In general, collections are more flexible than arrays and are better suited to scenarios where elements need to be added or removed dynamically. However, because of the more complex data structures used within collections, arrays can be more efficient than collections in some specific scenarios.
