SOLID - wikipedia SOLID This article is about the SOLID principles of object - oriented programming. For other uses, see Solid ( disambiguation ). SOLID Principles Single Responsibility Open / closed Liskov substitution Interface segregation Dependency inversion In object - oriented computer programming, the term SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable. The principles are a subset of many principles promoted by Robert C. Martin. Though they apply to any object - oriented design, the SOLID principles can also form a core philosophy for methodologies such as agile development or adaptive software development. The theory of SOLID principles was introduced by Martin in his 2000 paper Design Principles and Design Patterns, although the SOLID acronym itself was introduced later by Michael Feathers. Concepts Single responsibility principle a class should have only a single responsibility ( i.e. changes to only one part of the software 's specification should be able to affect the specification of the class ). Open / closed principle `` software entities... should be open for extension, but closed for modification. '' Liskov substitution principle `` objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program. '' See also design by contract. Interface segregation principle `` many client - specific interfaces are better than one general - purpose interface. '' Dependency inversion principle one should `` depend upon abstractions, ( not ) concretions.
