Can method overloading be considered a form of polymorphism in object-oriented programming?

Yes, method overloading can be considered a type of polymorphism in object-oriented programming, specifically — compile-time polymorphism (static polymorphism).

Overloading means having multiple methods with the same name but different parameters (types or number) within a single class. The compiler selects the appropriate method at compile time based on the arguments passed.

This differs from dynamic polymorphism (runtime polymorphism), which is implemented through method overriding and allows selecting the method implementation depending on the object type at runtime.

Example of overloading in Java:

class Calculator {
    int sum(int a, int b) {
        return a + b;
    }
    double sum(double a, double b) {
        return a + b;
    }
}

Here, the sum method is overloaded with different parameters — this is an example of static polymorphism.
