We can not override the constructor as the parent and child class can never have a constructor with the same name(The constructor name must always be the same as the Class name).
1. Overloadingis about the same method having different signatures. Overriding is about the same method, and same signature but different classes connected through inheritance. 2. Overloading is an example of compiler-time polymorphism and overriding is an example of run-timepolymorphism.
