Set (abstract data type) In computer science, a set is an abstract data type that can store unique values, without any particular order. It is a computer implementation of the mathematical concept of a finite set. Unlike most other collection types, rather than retrieving a specific element from a set, one typically tests a value for membership ...
In computer science, an abstract data type (ADT) is a mathematical model for data types, defined by its behavior (semantics) from the point of view of a user of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations. This mathematical model contrasts with data ...
Abstraction (computer science) In software engineering and computer science, abstraction is the process of generalizing concrete details, [1] such as attributes, away from the study of objects and systems to focus attention on details of greater importance. [2] Abstraction is a fundamental concept in computer science and software engineering ...
Set-builder notation can be used to describe a set that is defined by a predicate, that is, a logical formula that evaluates to true for an element of the set, and false otherwise. [ 2 ] In this form, set-builder notation has three parts: a variable, a colon or vertical bar separator, and a predicate. Thus there is a variable on the left of the ...
Recursive definition. Defining elements of a set in terms of other elements in the set. Four stages in the construction of a Koch snowflake. As with many other fractals, the stages are obtained via a recursive definition. In mathematics and computer science, a recursive definition, or inductive definition, is used to define the elements in a ...
Mutator method. In computer science, a mutator method is a method used to control changes to a variable. They are also widely known as setter methods. Often a setter is accompanied by a getter, which returns the value of the private member variable. They are also known collectively as accessors.
An interface in the Java programming language is an abstract type that is used to declare a behavior that classes must implement. They are similar to protocols. Interfaces are declared using the interface keyword, and may only contain method signature and constant declarations (variable declarations that are declared to be both static and final ...
Factory Method in LePUS3. In object-oriented programming, a factory is an object for creating other objects; formally, it is a function or method that returns objects of a varying prototype or class [ 1 ] from some method call, which is assumed to be new. [ a ] More broadly, a subroutine that returns a new object may be referred to as a factory ...
