Classes in Java support runtime polymorphism, and this property makes inheritance very powerful. What does runtime polymorphism allow in Java?Instruction: Choose the option that best answers the question. Answer ChoicesDisallows a particular class from being used as a parent class for other classesAllows the same method to have different implementations for different classesAllows one class to extend another class and derive that class’s methodsAllows a class that cannot directly be instantiated to extend other classes

Solution
Runtime polymorphism in Java allows the same method to have different implementations for different classes.
Similar Questions
Java classes support runtime polymorphism. Which statement describes what is possible with runtime polymorphism?Instruction: Choose the option that best answers the question. 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
