Solution

The correct statements about polymorphism in Java are:

a. Polymorphism allows an object to take on multiple forms at runtime. b. Polymorphism is achieved through method overriding.

These two statements are true because polymorphism, a key feature of object-oriented programming in Java, allows an object to behave in multiple ways. This is achieved through method overriding, where a subclass provides a specific implementation of a method that is already provided by its parent class.

The statements c and d are false. Polymorphism can be applied to both interfaces and classes in Java. And polymorphism is not limited to compile-time behavior only, it also applies to runtime behavior. This is known as dynamic method dispatch - the process by which a call to an overridden method is resolved at runtime, rather than compile-time.

Which of the following statements about inheritance and polymorphism is true in Java?Question 23Answera.Inheritance and polymorphism are independent concepts and do not impact each other.b.Inheritance is a prerequisite for polymorphism.c.Polymorphism can only be achieved through method overloading.d.Inheritance and polymorphism cannot be used together in the same program.

Which of the following statements about polymorphism are true? (Choose all that apply)  *2 pointsA. A reference to an object may be cast to a subclass of the object without an explicit cast.B. If a method takes a superclass of three objects, then any of those classes may be passed as a parameter to the method.C. A method that takes a parameter with type java.lang.Object will take any reference.D. All cast exceptions can be detected at compile-time.E. By defining a public instance method in the superclass, you guarantee that the specific method will be called in the parent class at runtime.

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
