What is the difference between method overloading and method overriding?
PICTURE THIS: RAG CHATBOT
Simple meaning
Overloading is compile-time: same method name, different parameter lists in the same class.
WHY — OOP instead of guessing?
Why interviewers care about OOP:
contrast on OOP, not two memorised paragraphs.
the developer, then one case where picking wrong hurts.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Overloading is compile-time: same
method name, different parameter lists in the same class.
- 2Overriding is runtime: a
subclass replaces a superclass method with the same signature.
- 3Overloading is resolved by
the compiler
- 4overriding uses the actual
object type.
- 5Common mistake

Key takeaway
Overloading is compile-time: same method name, different parameter lists in the same class. Overriding is runtime: a subclass replaces a superclass method with the same signature.
