The level of abstraction included in a programming language can influence its overall usability. The Cognitive dimensions framework includes the concept of abstraction gradient in a formalism. This framework allows the designer of a programming language to study the trade-offs between abstraction and other characteristics of the design, and how ...
The abstraction principle is mentioned in several books. Some of these, together with the formulation if it is succinct, are listed below. Alfred John Cole, Ronald Morrison (1982) An introduction to programming with S-algol: "[Abstraction] when applied to language design is to define all the semantically meaningful syntactic categories in the language and allow an abstraction over them".
A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.
Programming paradigms constitute the theoretical frameworks that shape the way software constructs are created and executed. Each paradigm embodies a unique approach to organizing and structuring programming logic, often promoting particular forms of abstraction and compositional structures that align with their underlying principles.
In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages, where the document represents source code, and to markup languages, where the document represents data.
In object oriented programming, objects provide a layer which can be used to separate internal from external code and implement abstraction and encapsulation. External code can only use an object by calling a specific instance method with a certain set of input parameters, reading an instance variable, or writing to an instance variable.
AHA programming assumes that both WET and DRY solutions inevitably create software that is rigid and difficult to maintain. Instead of starting with an abstraction, or abstracting at a specific number of duplications, software can be more flexible and robust if abstraction is done when it is needed, or, when the duplication itself has become ...
The rule was popularised by Martin Fowler in Refactoring [1] and attributed to Don Roberts. Duplication is considered a bad practice in programming because it makes the code harder to maintain . When the rule encoded in a replicated piece of code changes, whoever maintains the code will have to change it in all places correctly.
