Q:

Define a superclass named Media and a subclass of Media named Video

0

Define a superclass named Media containing:

- A protected instance variable named title of type String.

- A protected instance variable named length of type double.

- A full-argument constructor to assign the values of data members.

- A no-argument constructor that calls the full-argument constructor and sends "No Title" & 1.0 as parameters.

- Set and get methods for title and length.

- Override toString() to returns a string representation of the instance variables.

 

Define a subclass of Media named Video . The class should have the following public methods:

- A private instance variable named quality of type String.

- A full-argument constructor to send title and length to the super constructor and assign the value of quality.

- A one-argument constructor to assign the value of quality.

- Set and get methods for quality.

- Override toString() to returns a string representation of the instance variables (use toString() of superclass).

 

Define a driver class MediaPlayer that contains main method. Declare objects of type Media and Video using all constructors. Then, print the objects.
