Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, 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).
In object oriented programming, the factory method pattern is a creational pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact class. Rather than by calling a constructor, this is done by calling a factory method to create an object. Factory methods can either be specified in an ...
A Java virtual machine ( JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java ...
GRASP (object-oriented design) General Responsibility Assignment Software Patterns (or Principles ), abbreviated GRASP, is a set of "nine fundamental principles in object design and responsibility assignment" [1] : 6 first published by Craig Larman in his 1997 [citation needed] book Applying UML and Patterns .
In object-oriented programming, association defines a relationship between classes of objects that allows one object instance to cause another to perform an action on its behalf. This relationship is structural, because it specifies that objects of one kind are connected to objects of another and does not represent behaviour . Top: A ...
Types of nested classes in Java. In Java there are four types of nested class: Static. Static member class, also called static nested classes – They are declared static. Like other things in static scope (i.e. static methods), they do not have an enclosing instance, and cannot access instance variables and methods of the enclosing class.
In computer programming, operator overloading, sometimes termed operator ad hoc polymorphism, is a specific case of polymorphism, where different operators have different implementations depending on their arguments. Operator overloading is generally defined by a programming language, a programmer, or both.
von Neumann architecture. The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [1] The document describes a design architecture for an electronic digital computer ...
