Java uses classical inheritance (extends) to share behavior. Go favors composition, embedding one struct inside another to reuse functionality.
| Feature | Java (extends) |
Go (composition) |
|---|---|---|
| Inheritance method | class Mage extends Character |
type Mage struct { Character } |
| Method override | @Override annotation |
Redefine method on outer struct |
| Multiple inheritance | ❌ Not allowed | ✅ Via multiple embeddings |
Go avoids deep inheritance trees and tight coupling. Instead, it promotes flexible design with composition, a cleaner, more scalable alternative.
