the digits 12 to 14 are the second part of the IDĪnd here is a test that proves that an example VIN works: package vin_testįunc TestVIN_Manufacturer(t *testing. if the last digit of the manufacturer ID is a 9 Inheritance describes the ability to create new classes based on an existing class. Consider two objects, customer and account in a program. Objects can also represent user-defined data such as vectors, time, and lists. They may represent a place, a person, an account, a table of data, or anything that the program needs to handle. Encapsulation means that a group of related properties, methods, and other members are treated as a single unit or object. Objects are the basic run-time bodies in an object-oriented framework. The unique vehicle identification number of every car includes-beside a “running” (i.e., serial) number-information about the car, such as the manufacturer, the producing factory, the car model, and if it is driven from the left- or right-hand side.Ī function to determine the manufacturer code might look like this: package vin Visual Basic provides full support for object-oriented programming including encapsulation, inheritance, and polymorphism. Tip: The 'Don't Repeat Yourself' (DRY) principle is about reducing the. OOP makes it possible to create full reusable applications with less code and shorter development time. OOP helps to keep the PHP code DRY 'Don't Repeat Yourself', and makes the code easier to maintain, modify and debug. Case Study in Golang OOP: Reading the Manufacturer Code from a Vehicle Identification Number (VIN) OOP provides a clear structure for the programs. This Golang tutorial will take a simple example and demonstrate how to apply the concepts of binding functions to types (aka classes), constructors, subtyping, polymorphism, dependency injection, and testing with mocks.

Nevertheless, in Go, object-oriented patterns are still useful for structuring a program in a clear and understandable way. Is Go object-oriented? Can it be? Go (or “Golang”) is a post-OOP programming language that borrows its structure (packages, types, functions) from the Algol/Pascal/Modula language family.
