Liststring

ListString is a term used to describe a collection that stores an ordered sequence of strings. In programming contexts, it may refer to either a dedicated class that wraps a dynamic array of strings, or simply a semantic alias for a standard list type whose elements are strings.

Elements are typically indexed, and the collection provides operations for adding, removing, retrieving by index, and iterating. Depending on the language, it may be mutable or immutable, and strings may be stored by value or by reference.

Common operations include add(string), insert(index, string), remove(index or string), get(index), set(index, string), size or length, isEmpty, and clear. Utility methods often include join(delimiter) to produce a single string, toArray, and support for sorting, filtering, and mapping.

Typical use cases include tokenizing input into a list of words, accumulating user-provided values, parsing configuration entries, and handling CSV-like data where a row is represented as a ListString. Design considerations cover memory usage, null handling, string encoding, and performance characteristics of concatenation and element access.

In Java or Kotlin, ListString may be implemented as a wrapper around List<String> or as a type alias; in other languages it may correspond to an immutable list type. The exact API depends on the language and library.
