Go Inheritance and Polymorphism

• Go Object Oriented Programming

Polymorphism

Polymorphism is available in Go, but it is implemented differently than in other object-oriented languages.

In other OOP languages, there is a formal extends language keyword or other formal syntax that expresses the inheritance relationship between classes. In Java, the inheritance is formally declared with the extends keyword:

class SomeSubclass extends SomeSuperclass {
  ...
}

In Python, we formally declare that a class extends other class with this syntax:

class SomeSubclass(SomeSuperclass):
  ...

o, in that it does not imply formal inheritance at language level, which is not available in Go. Polymorphism in Go is implemented using interfaces.
