polymorphism

🎭 Polymorphism in Java vs Go

Polymorphism means many forms — the ability for different types or method signatures to respond differently to the same operation.

There are two main types:

Type	Description	Java Support	Go Support
Method Overriding	Subclass overrides a method of superclass	✅	✅ (via struct + method)
Method Overloading	Same method name, different parameters	✅	❌ (Go doesn’t support overloading)

---

🧬 Method Overriding (Runtime Polymorphism)

This allows subclasses or types to provide their own implementation of a method defined in the parent class or interface.

📂 See:

• PolymorphismExample.java
• interfaces.go

---

🌀 Method Overloading (Compile-Time Polymorphism)

This allows multiple methods with the same name but different parameters.

📂 Only in Java:

• PolymorphismExample.java

🔍 Key Insight

• Java supports both overriding and overloading, giving you flexibility at both compile-time and runtime.
• Go keeps things minimal and only supports overriding behavior through interfaces and method values — no overloading allowed.

🚫 Go keeps it simple: one function name, one signature. If you need variations, use optional parameters via structs or variadic functions.
