3Which types of Polymorphism is there?-Compile Time (Static)
-> can be archived by Method Overloading or Constructor Overloading
- Runtime (Dynamic)
-> can be archived by Method Overriding
4How can Method Overloading or Constructor Overloading be archived?- By keeping the same method name and changing:
-number of parameters
-type of parameters
- order of parameters
Da der Compiler immer eine Methode basierend auf dem Kontext in der gleichen Klasse auswählt, ist Overloading nicht für Methoden in unterschiedlichen Klassen vorgesehen.

Runtime (Dynamic)
Method Overriding
- Can be archieved in Inheritance by reimplementing the parent class method in Child class
class: printer

};
class Greeter inherits from printer class
@Overriden
print(){
Syso("HI");
}
