Object-oriented programming concepts can be implemented in Golang using structs, methods, encapsulation, inheritance, and polymorphism.

• Use structs to define objects and their properties

• Methods can be defined on structs to encapsulate behavior

• Encapsulation can be achieved by using private and public fields

• Inheritance is not directly supported in Golang, but composition can be used to achieve similar functionality

• Polymorphism can be achieved through interfaces and type assertio...read more
