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

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
Solution
The statement that best describes what is possible with runtime polymorphism in Java is: "Calls to overridden methods are resolved at runtime, hence methods invoked on an object will use the correct implementation based on object type". This is because in runtime polymorphism (also known as dynamic method dispatch), the JVM determines the proper methods to call at the program’s run time, not at the compile time.
