Given the base class named Quiz and the derived class named Essay, write a statement to show inheritance between these classes.

1- Design a class named Rectangle to represent a Rectangle. The class contains: • three variables integer data field named height, integer data filed named width and integer data filed named length. The default values are 1 for height, length, and width are 1.0 for each of them respectively. • A no-arg constructor that creates a default Rectangle. • A constructor that creates a Rectangle with the specified height, length and width. • A method named getVolume() that returns the volume of this Rectangle. (Volume = height * width * length) %3! 2- Write a test program called Test Rectangle that: • Creates two Rectangle objects: one object with height 11, length 5, and width 7, the other object with height 10, length 2 and width 6 • Display the volume of each Rectangle object.

Design a Ship class that has the following members:• A field for the name of the ship (a string).• A field for the year that the ship was built (a string).• A constructor and appropriate accessors and mutators.• A toString method that displays the ship's name and the year it was built.Disign a CruiseShip class that extends the Ship class. The CruiseShip class should have thefollowing members:• A field for the maximum number of passengers (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CruiseShipclass's toString method should display only the ship's name and the maximum number ofpassengers.Design a CargoShip class that extends the Ship class. The CargoShip class should have thefollowing members:• A field for the cargo capacity in tonnage (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CargoShipclass's…
