Oracle PL/SQL implements collections as programmer-defined types [1] Python: some built-in, others implemented in the collections library.NET provides the ICollection and IReadOnlyCollection interfaces and implementations such as List<T>. Rust provides the Vec<T> [2] and HashMap<K, V> [3] structs in the std::collections namespace. [4]
The text string "comment" might be repeated in the label, the HTML tag, in a read function name, a private variable, database DDL, queries, and so on. A DRY approach eliminates that redundancy by using frameworks that reduce or eliminate all those editing tasks except the most important ones, leaving the extensibility of adding new knowledge ...
Collection implementations in pre-JDK 1.2 versions of the Java platform included few data structure classes, but did not contain a collections framework. [4] The standard methods for grouping Java objects were via the array, the Vector, and the Hashtable classes, which unfortunately were not easy to extend, and did not implement a standard member interface.
One of the very useful aspects of Python is the concept of collection (or container) types. In general a collection is an object that contains other objects in a way that is easily referenced or indexed. Collections come in two basic forms: sequences and mappings. The ordered sequential types are lists (dynamic arrays), tuples, and strings.

(August 2010) (Learn how and when to remove this message) clone() is a method in the Java programming language for object duplication . In Java, objects are manipulated through reference variables, and there is no operator for copying an object—the assignment operator duplicates the reference, not the object.
Duplicate code is most commonly fixed by moving the code into its own unit (function or module) and calling that unit from all of the places where it was originally used.. Using a more open-source style of development, in which components are in centralized locations, may also help with duplicati
Code is refactored for readability and maintainability. In particular, hard-coded test data should be removed from the production code. Running the test suite after each refactor ensures that no existing functionality is broken. Examples of refactoring: moving code to where it most logically belongs; removing duplicate code; making names self ...
