1. Overriding and Access Modifiers
The access modifierfor an overriding method can allow more, but not less, access than the overridden method. For example, a protected instance method in the superclass can be made public, but not private, in the subclass. Doing so will generate a compile-time error.
2. Final methods can not be overridden
If we don’t want a method to be overridden, we declare it as final. Please see Using Final with Inheritance. Output
3. Static methods can not be overridden(Method Overriding vs Method Hiding):
When you define a static method with the same signature as a static method in the base class, it is known as method hiding. The following table summarizes what happens when you define a method with the same signature as a method in a super-class.
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.
