1)is overloading is related to one class only or it can be extended in the derived class,also

1. Both. One class may have two or more methods with the same name but different signatures. When this happens it is said to be overloaded. Likewise a class may have a method with the same name and a different signature than one inherited from another class, this is still overloading.

2. See HashMap for one example.
