  2. Bridge pattern - Wikipedia

    en.wikipedia.org/wiki/Bridge_pattern

    [2] An abstraction and its implementation should be defined and extended independently from each other. A compile-time binding between an abstraction and its implementation should be avoided so that an implementation can be selected at run-time. When using subclassing, different subclasses implement an abstract class in different ways.

    //By default, all methods in all classes are concrete, unless the abstract keyword is used. public abstract class Demo {// An abstract class may include abstract methods, which have no implementation. public abstract int sum (int x, int y); // An abstract class may also include concrete methods. public int product (int x, int y) {return x * y;}} //By default, all methods in all interfaces are ...

  4. Collection (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Collection_(abstract_data...

    In computer programming, a collection is an abstract data type that is a grouping of items that can be used in a polymorphic way. Often, the items are of the same data type such as int or string . Sometimes the items derive from a common type; even deriving from the most general type of a programming language such as object or variant .

  5. Class (computer programming) - Wikipedia

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

    A class consisting of only pure virtual methods is called a pure abstract base class (or pure ABC) in C++ and is also known as an interface by users of the language. [13] Other languages, notably Java and C#, support a variant of abstract classes called an interface via a keyword in the language.

  6. Metaclass - Wikipedia

    en.wikipedia.org/wiki/Metaclass

    In Python, the metaclass - type - controls these details of Car's behavior. They can be overridden by using a different metaclass instead of type. The above example contains some redundant code to do with the four attributes make, model, year, and color. It is possible to eliminate some of this redundancy using a custom metaclass.

  7. Factory (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Factory_(object-oriented...

    In class-based programming, a factory is an abstraction of a constructor of a class, while in prototype-based programming a factory is an abstraction of a prototype object. A constructor is concrete in that it creates objects as instances of one class, and by a specified process (class instantiation), while a factory can create objects by instantiating various classes, or by using other ...

    The actual statement is in columns 7 through 72 of a line. Any non-space character in column 6 indicates that this line is a continuation of the prior line. A 'C' in column 1 indicates that this entire line is a comment. Columns 1 though 5 may contain a number which serves as a label.

    Interfaces and abstract classes are similar. The following describes some important differences: An abstract class may have member variables as well as non-abstract methods or properties. An interface cannot. A class or abstract class can only inherit from one class or abstract class. A class or abstract class may implement one or more interfaces.
