public class ArrayOfStringsSerDe
extends ArrayOfItemsSerDe<String>
```
Methods of serializing and deserializing arrays of String. This class serializes strings in UTF-8 format, which is more compact compared to ArrayOfUtf16StringsSerDe. In an extreme case when all strings are in ASCII, this method is 2 times more compact, but it takes more time to encode and decode by a factor of 1.5 to 2.
