Object-oriented programming language - Object-oriented programming language An object-oriented programming language is one that allows or encourages, to some degree, object-oriented programming methods. See object-oriented programming for details about those methods. Though Simula (1967), a language created for making simulation programs, was probably the first language to have the primary features of an object-oriented language, Smalltalk is arguably the canonical example, and the one with which much of the theory of object-oriented programming was developed. These languages include "pure" object-oriented languages such as Smalltalk and Ruby, which were designed specifically to facilitate--even enforce--object-oriented methods; languages such as Java, Eiffel, and Python, which are primarily designed for object-oriented programming but have some procedural elements; and languages such as C++ and Perl, which are historically procedural languages that have been extended with.
How to program in object-oriented languages - How to program in object-oriented languages Programming in object-oriented languagess is more a question of how to design your code than how to write specific procedures. Traditionally, programming is taught as a bottom-up approach. This model fits very well with procedural programming, even more with non-modular languages, such as Fortran and Basic. Object-oriented concepts, however, should be learned and used in a top-down approach, starting from modeling objects and object interactions. Although some object-oriented languages follow the object metaphor down to the statement level, like Smalltalk, the most widely known languages of today, i.e. C++, Object Pascal and Java follow an almost procedural notation. So, to devise a good object-oriented program, one should first devise an effective model and later implement the model in the chosen language..

Object (object-oriented programming) - Object (object-oriented programming) In computer science, an object is something that has an identity, a state, and a behaviour. The state is encoded in instance variables (data members), the behaviour is encoded in methodss (member functions). Objects are bundles of related variables and methods and are often used to model real-world objects. Objects can be affected by eventss. Object-oriented programs typically contain a large number of objects. It could be said that a class is a blueprint, and an object is a house. An object belonging to a class is referred to as an instance of the class. If humanity were a class, then [you] would be an instance of the class [human]. Overview of Identities, States, and, Behaviours The identity of an object from the.
Java programming language - Java programming language The Java language is an object-oriented programming language created by James Gosling and other engineers at Sun Microsystems. It was developed in 1991, as part of the Green Project, and officially announced on May 23, 1995, at SunWorld; being released in November. Gosling and friends initially designed Java, which was called Oak at first (in honour of a tree outside Gosling's office), to replace C++ (although the feature set better resembles that of Objective C). More on the history of Java can be found in the article about the Java platform, which includes the language, the Java virtual machine, and the Java API. Sun controls the Java specification and holds a trademark on the Java name. Table of contents showTocToggle("show","hide") 1 Overview 1.1 Object.
Io programming language - Io programming language The Io programming language is a pure object-oriented language inspired by Smalltalk, Self and NewtonScript. Features: Prototype base object model Dynamic typing Actors for concurrency All values are objects.
Haskell programming language - Haskell programming language In the 1980s, a committee was formed to create a standardized functional programming language with non-strict semantics. Haskell, named after the logician Haskell Curry, was the result of those deliberations. The latest semi-official language standard is Haskell 98, intended to specify a minimal, portable version of the language for teaching and as a base for future extensions. The language continues to evolve rapidly, with Hugs and GHC (see below) representing the current de facto standard. Interesting Haskell features include support for recursive functions and datatypes, pattern matching and list comprehensions. The combination of such features can make functions which would be difficult to write in a procedural programming language almost trivial to implement in Haskell. The language is, as of 2002, the functional language.

GRASS programming language - GRASS programming language GRASS (GRAphics Symbiosis System) was a programming language created to script visual animations in 2D. GRASS was similar to the BASIC programming language in syntax, but added numerous instructions for specifying 2D object animation, including scaling, translation, rotation and color changes over time. It quickly became a hit with the artistic community who were experimenting with the new medium of computer graphics, and will remain most famous for its use by Larry Cuba to create the original "attacking the death star will not be easy" animation in Star Wars. History The original version of GRASS was developed by Tom DeFanti for his 1974 Ohio State University Ph.D. thesis. It was developed on a PDP-11/45 driving a Vector General 3DR display, and as the name.
Forth programming language - Forth programming language Forth is a computer programming environment developed by Chuck Moore then at the US National Radio Astronomy Observatory (NRAO) during the 1960s, and later formalized as a programming language in 1977, and standardized by ANSI in 1994. It features both interactive execution of commands (making it suitable as a shell for systems that lack a more formal operating system), as well as the ability to compile sequences of commands into threaded code for later execution. Its name is derived from Mr. Moore's belief that it was a "fourth-generation computer language" on a computer whose file system allowed only five-letter identifiers. Forth offers a stand-alone programming environment, consisting of a stack oriented interactive incremental interpreter/compiler. Programming is done by extending the language with 'words' (the.
Eiffel programming language - Eiffel programming language Eiffel is an object-oriented (OO) programming language which emphasizes the production of robust software. Many find its syntax to be reminiscent of Pascal. Eiffel is strongly statically typed, with automatic memory management (typically implemented by garbage collection). Created in 1985, Eiffel is a mature OO language with development systems available from four different suppliers. Despite this maturity and a generally excellent reputation among those who are familiar with the language, Eiffel has failed to gain much interest from software developers. The reasons for this lack of interest are unclear, and are a topic of frequent discussion within the Eiffel community. Distinguishing characteristics of Eiffel include Design by Contract™, liberal use of implementation inheritance including multiple inheritance, value types implemented via value semantics, and generic.
Euphoria programming language - Euphoria programming language Euphoria is a PC programming language created with the following design goals: Simplicity - To be easier to learn and use than BASIC, with more-consistent high-level constructs. Uses flat-form 32-bit memory to avoid complicated memory management and size/addressing limits. Power - To provide low-level capabilities needed to access the OS and BIOS for professional development, but be more structured and less terse than a low-level language, making low-level programming less dangerous. Safety - Extensive debugging support and run-time error-handling; automatic subscript checking, type-checking, and memory handling. Flexibility - User-defined type support, with variables as loosely or strictly typed as desired. Object-oriented programming can be accomplished by defining objects as types (subsets of the sequence, which is a general-purpose collection). Ease of Development - Interpreted,.
Dylan programming language - Dylan programming language Dylan is a dynamic programming language created by a group within Apple Computer. It was originally intended for use with Apple's Newton computer but their implementation did not reach sufficient maturity to ship it as a product (though it did ship as a technology demonstration). However, the language design was intriguing enough that at least one company and a university implemented compilers and development environments for Dylan that were quite good. The Dylan language is notable for being purely object-oriented: every value is an object. http://directory.google.com/Top/Computers/Programming/Languages/Dylan/?tc=1.
Delphi programming language - Delphi programming language Delphi is a programming language and software development environment. It is produced by Borland (known for a time as Inprise). The Delphi language, formerly known as the Object Pascal Language (the Pascal with object-oriented extensions) originally targeted only Microsoft Windows, but now builds native applications for Linux and the Microsoft .NET Framework as well (see below). Its most popular use is the development of desktop and enterprise database applications, but as a general purpose development tool it is capable of and used for most types of development projects. It was one of the first of what came to be known as RAD tools, for Rapid Application Development, when released in 1995. Delphi 2, released a year later, supported 32-bit Windows environments, and a C++.
Ada programming language - Ada programming language Ada is a structured, compiled, statically typed programming language, designed by Jean Ichbiah of Cii Honeywell Bull in the 1970s. It is positioned to address much the same tasks as C or C++. Ada was named after Lady Ada Lovelace, the first computer programmer.

Notable features of Ada include Strong typing, run-time checking, parallel processing, exception handling, and genericss. Ada 95 added support for.
AmigaE programming language - AmigaE programming language AmigaE, or very often simply E, is a programming language created by Wouter van Oortmerssen on the Amiga. He has since moved to develop the SHEEP programming language for the new AmigaDE platform. Although development ended in 1994, AmigaE still has a huge following since it is easy to understand, powerful and fast. AmigaE is a combination of features from a number of languages, but follows the original C programming language in terms of features and concepts most closely. AmigaE's main benefit is that it compiles and runs very fast, allowing it to be used in place of a scripting language. It is fast primarily by being feature-light, and AmigaE has only the basic features suited to writing larger programs. All of these features.
Aspect-oriented programming - Aspect-oriented programming In computer science, aspect-oriented programming is a programming paradigm that centers around constructs called aspects, which describe concerns of a separate set of objects, classes or functions. Aspect-oriented programming is not limited to object-oriented programming, though. An aspect describes points (join points) in a program, where the aspect will affect the program's semantics. A set of join points is called a (pointcut). Now methodss or functions may be called in the aspect (called advices then), that may implement behaviour that would normally crosscut behaviour of the core concern of the application. For example, in a credit card application billing would be a core concern, and logging and persistence of participating objects would be concerns, that most likely crosscut the whole object hierarchy. Separating these concerns.
C Sharp programming language - C Sharp programming language C# (pronounced see-sharp) is an object-oriented programming language developed by Microsoft as part of their .NET initiative. Microsoft based C# on C++ and the Java programming language. C# was designed to balance power (the C++ influence) with rapid development (the Java influence).

Categorical list of programming languages - Categorical list of programming languages This is a list of programming language grouped by category. See also Alphabetical list of programming languages Chronological list of programming languages Generational list of programming languages Assembly languages directly correspond to a machine language (see below) in order to allow machine code instructions to be written in a form understandable by humans. Assembly languages allow programmers to use symbolic addresses which are later converted to absolute addresses by the assembler. Most assemblers also allow for macros and symbolic constants as well. SSK (Sistema Simvolicheskogo Kodirovaniya, or "System of symbolic coding") for Minsk family of computers. AKI (AvtoKod Ingenera, i.e., "engineer's autocode") for Minsk family of computers was half-step away from assembly languages and doesn't really fit into any other categories in this.
CLU programming language - CLU programming language CLU, a programming language created at MIT by Barbara Liskov [1] in 1974-1975, was the first language which had iterators. Syntax of CLU was based on Pascal, but strongly simplified. CLU uses a concept called a "cluster" which is a slight generalisation of "modules" as seen in Modula-2, early Ada, etc. This is about the closest you can get to object-oriented programming without actually being there. Ruby borrowed many concepts from CLU and has similar syntax..
