Object-oriented programming in Go

As Go does not support all object-oriented features, it cannot replace an object-oriented programming language fully. However, it can mimic some object-oriented concepts.

First of all, a Go structure with its type methods is like an object with its methods. Second, interfaces are like abstract data types that define behaviors and objects of the same class, which is similar to polymorphism. Third, Go supports encapsulation, which means it supports hiding data and functions from the user by making them private to the structure and the current Go package. Lastly, combining interfaces and structures is like composition in object-oriented terminology.

If you really want to develop applications using the object-oriented methodology, then choosing Go might not be your best option. As I am not really into Java, I would suggest looking at C++ or Python instead. The general rule here is to choose the best tool for your job.
