In Go programming, defining and using structured types and objects is typically done through structs. Unlike traditional object-oriented languages that use classes, Go adopts a more minimalist approach. This guide explores the differences between Go's structs and classes from other languages, particularly focusing on how they are used for defining and managing data.
Definition and Basic Usage
In Go, a struct
is a composite data type that groups together variables (fields) under a single name. These fields can have different types and are used to model real-world entities. Unlike classes in object-oriented languages, structs do not support inheritance, but they can be used with methods to define behavior.

Definition and Basic Usage
In object-oriented languages like Java or C++, a class
is a blueprint for creating objects. It encapsulates data for the object and methods to manipulate that data. Classes support inheritance, allowing new classes to be based on existing ones.
Example (Java):
Key Points:
Inheritance vs. Composition
Encapsulation
Method Association
Go's structs offer a more straightforward approach to defining structured types compared to classes in traditional object-oriented languages. By emphasizing composition over inheritance and simplifying encapsulation, Go’s structs cater to different design philosophies while maintaining simplicity and efficiency. Understanding these differences is crucial for effectively leveraging Go's features for various programming needs.
