Kas saaksite selgitada, mida tähendab termin 'heterogeenne andmetüüp'?

Term «heterogeneous data type» refers to a structure or collection that can contain elements of different data types.

Unlike homogeneous collections (e.g., arrays of the same type), heterogeneous collections allow storing, for example, numbers, strings, objects, etc. together.

Example in Java — using a collection with type Object:

List<Object> list = new ArrayList<>();
list.add("string");
list.add(123);
list.add(new Date());

Here, the list contains different data types, making it heterogeneous.

Heterogeneous types are useful when working with diverse data, but require additional processing and type checking during use.
