Is there a way to avoid type-checking in this scenario?
- by Prog
I have a class SuperClass with two subclasses SubClassA and SubClassB. I have a method in a different class which takes a SuperClass parameter.
The method should do different things depending on the type of the object it receives. To illustrate:
public void doStuff(SuperClass object){
// if the object is of type SubClassA, do something.
// if it's of type SubClassB, do something else.
}
I want to avoid type-checking (i.e. instanceof) because it doesn't feel like proper OO design.
But I can't figure out how to employ Polymorphism to elegantly solve this problem.
How can I solve this problem elegantly?
