What is the main difference?
Short answer. Overloading changes the parameter list in one class; overriding keeps the signature in a child class.
When is each decided?
Overloading at compile time, overriding at run time.
The difference
| Point | Overload | Override |
|---|---|---|
| Where | same class | child class |
| Parameters | differ | same |
| Decided | compile time | run time |
Remember
| Overload: new parameters |
| Override: same signature |
They sound alike, but differ. Three differences. Overload is one class, override a child. Overload changes parameters, override keeps them. Overload is fixed at compile time. Overload means new parameters. Override keeps the signature.
