  2. Container (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Container_(abstract_data_type)

    In computer science, a container is a class or a data structure [1] [2] whose instances are collections of other objects. In other words, they store objects in an organized way that follows specific access rules. The size of the container depends on the number of objects (elements) it contains.

  3. Abstraction (computer science) - Wikipedia

    en.wikipedia.org/wiki/Abstraction_(computer_science)

    A decision to differentiate DairyAnimal would change the detailed analysis but the domain and legacy analysis would be unchanged—thus it is entirely under the control of the programmer, and it is called an abstraction in object-oriented programming as distinct from abstraction in domain or legacy analysis.

  4. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

  5. Type system - Wikipedia

    en.wikipedia.org/wiki/Type_system

    Even a type can become associated with a type. An implementation of a type system could in theory associate identifications called data type (a type of a value), class (a type of an object), and kind (a type of a type, or metatype). These are the abstractions that typing can go through, on a hierarchy of levels contained in a system.

  6. Set (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Set_(abstract_data_type)

    The Tcl Tcllib package provides a set module which implements a set data structure based upon TCL lists. The Swift standard library contains a Set type, since Swift 1.2. JavaScript introduced Set as a standard built-in object with the ECMAScript 2015 [10] standard. Erlang's standard library has a sets module.

  7. Class (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Class_(computer_programming)

    In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages , but generally the shared aspects consist of state ( variables ) and behavior ( methods ) that are each either associated with a particular object or with all objects of that class.

  8. Java collections framework - Wikipedia

    en.wikipedia.org/wiki/Java_collections_framework

    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.

  9. Capacity of a set - Wikipedia

    en.wikipedia.org/wiki/Capacity_of_a_set

    In mathematics, the capacity of a set in Euclidean space is a measure of the "size" of that set. Unlike, say, Lebesgue measure , which measures a set's volume or physical extent, capacity is a mathematical analogue of a set's ability to hold electrical charge .
