Method is a term used within computer science to describe a step-by-step procedure, or algorithm, used to achieve a specific goal. It can also refer to the name given to a subroutine, or set of code, that executes a set of instructions. A method can be part of an object-oriented approach, where it is known as a method, or be part of a procedural approach, where it is known as a function.
Methods often allow for related functionality to be grouped together instead of spreading code across multiple locations. This allows for code to be easier to locate and maintain, resulting in greater efficiency when developing programs. Additionally, encapsulation of code into methods allows for code reuse and the development of libraries. This code reuse increases the efficiency of writing programs, and also allows for future software applications to be quickly and easily built upon existing code.
In object-oriented programming, a method is a section of code that is attached to a specific object. This code is called whenever the object needs to perform a particular action. By using a method, developers can define the properties and behavior of an object without needing to constantly rewrite code whenever an object’s behavior needs to be changed. This object-oriented approach to programming allows for data and code to be better organized, as the data and code related to a particular object can be easily found within the same location.
Methods are a cornerstone of efficient programming, and understanding the development and usage of methods is essential for computer science professionals. As such, methods are used extensively in development projects, and are usually the first element to be considered when developing a software solution.
