So, overloading functions is a type of polymorphism ?

@lilswetambz 5 жыл бұрын

making a copy of another method but with different arguments is NOT polymorphism!

@Retrosenescent 4 жыл бұрын

Yes. Polymorphism has two components: method overloading and method overriding.

Would it be safe to say this is like a case statement, logic never changes but argument is whatever you want it to be?

@Delstar 5 жыл бұрын

Yes. But generally it is better because it's not as messy with many different arguments. (Having 50 unique arguments in a case system would look awful)

@illmatic33 5 жыл бұрын

@@Delstar but how is this different then? How argument in this example (add 47 more animals) different from a case statement? You are passing a param. "Case animals"... When dogs...execute bark, when cat... Execute meow... And so on. Maybe I am misunderstanding something here...

Polymorphism occurs at run time or debug time or compile time?

@ramyar3921 4 жыл бұрын

Runtime

@awesomedavid2012 11 ай бұрын

It depends. Functional overloading in a statically styped language occurs at compile time when the compiler detects the type and chooses which function to call. When it comes to something like: interface A Type B implements A Type C implements A obj: A = B() A.method That happens at runtime because the compiler has no idea which type (B or C)'s method is going to actually be called. It just knows they both have that method so the code will be valid at runtime. But the choosing of the method happens at runtime.

@drakulea4301 5 ай бұрын

ok but you're missing the essence and you're kinda mixing stuff with inheritance here.. The basis of polym is not that you have multiple copies of your function in each type that inherits form Animal( that's inheritance), but rather that you have a method pet(Animal a) in another class, and any object of a type that inherits from class Animal will be suitable for that method. ( they key point here is that you can only have the class Animal and pet method and classes that are still not existent can comply to the pet's method signature by inheriting from Animal). Polymorphism can be achieved through interfaces, abstract classes, or regular (concrete) classes, but the essence remains the same: treating objects of different types in a uniform way. In the broader context, polymorphism is about writing code that can work with objects of different types in a unified manner. Whether you achieve this through interfaces, abstract classes, or regular classes with inheritance, the goal is to create more flexible and reusable code that can accommodate various types of objects without knowing their specific implementations.

@drakulea4301 5 ай бұрын

nope I feel as many people don't grasp the essence of polymorphism and they just see that polymorphism is child classes overiding methods from parents or interfaces, but in reality they are truly missing the point .. which is to create more flexible and reusable code that can accommodate various types of objects. so the power is the fact that you can lets say have a method pet(Animal a) in any other class and any object of a type that inhertis from Animal would be propper argument for that method.
