Which of these allows compile-time polymorphism?OptionsMethod overloadingMethod overridingBothNone of the above
Solution
The answer is "Method overloading".
Method overloading allows compile-time polymorphism. This is because method overloading is determined at compile time. In method overloading, methods of the same class shares the same name but each method must have different number of parameters or parameters having different types and order. The compiler uses these differences to determine which version of the method to call, and this decision is made when the code is compiled.
On the other hand, method overriding is a feature that allows runtime polymorphism. In method overriding, a subclass provides a specific implementation of a method that is already provided by its parent class. The method in the subclass must have the same name, return type, and parameters as the one in its parent class. The determination of which method in the class hierarchy to call is made at runtime.
So, the correct answer is "Method overloading".
