Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Programming language – a formal language designed to communicate instructions to a machine, particularly a computer Scripting language – a type of programming language which typically is interpreted at runtime rather than being compiled; Query language – a language used to make queries in databases and information systems; Transformation ...
The various object-oriented programming languages enforce member accessibility and visibility to various degrees, and depending on the language's type system and compilation policies, enforced at either compile time or runtime. For example, the Java language does not allow client code that accesses the private data of a class to compile. [12]
Programming language – formal constructed language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.
Each of these programming styles has contributed to the synthesis of different programming languages. [40] A programming language is a set of keywords, symbols, identifiers, and rules by which programmers can communicate instructions to the computer. [41] They follow a set of rules called a syntax. [41]
In computer science, program synthesis is the task to construct a program that provably satisfies a given high-level formal specification.In contrast to program verification, the program is to be constructed rather than given; however, both fields make use of formal proof techniques, and both comprise approaches of different degrees of automation.

The meta-model is the part of the system that implements the programming system itself, and developers can use the meta-model to do things like walk through, examine, and modify code in the running system, or find all the instances of a certain kind of structure (e.g., all instances of the Method class in the meta-model).
