Select the correct answerIn Java, what concept allows us to implement runtime polymorphism?OptionsMethod overridingMethod overloadingConstructorsStatic methods
Solution
The correct answer is Method overriding. This concept in Java allows us to implement runtime polymorphism. Here's why:
-
Polymorphism in Java is a concept by which we can perform a single action in different ways. Polymorphism is derived from 2 Greek words: poly and morphs. The word "poly" means many and "morphs" means forms. So polymorphism means many forms.
-
There are two types of polymorphism in Java: compile-time polymorphism and runtime polymorphism. We can perform polymorphism in java by method overloading and method overriding.
-
If you overload a static method in Java, it becomes the compile-time polymorphism. If you override a method in Java, it becomes the runtime polymorphism.
-
Therefore, the concept that allows us to implement runtime polymorphism in Java is Method overriding.

Answer ChoicesMultiple implementations can exist for methods with the same name, with the same input arguments and return valuesCalls to overridden methods are resolved at runtime, hence methods invoked on an object will use the correct implementation based on object typeExactly one implementation can exist for a method with a certain name, and all derived classes have access to these implementationsMethods invoked on objects of the base class type will invoke the base class method implementations
