In Java create the following: Design a Ship class that 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 Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following 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 CruiseShip class’s toString method should display only the ship’s name and the maximum number of passengers Design a CargoShip class that extends the Ship class. The CargoShip class should have the following 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 CargoShip class’s toString method should display only the ship’s name and the ship’s cargo capacity Demonstrate the classes in a program that has a Ship array Assign various Ship, CruiseShip, and CargoShip objects to the array elements The program should then step through the array, calling each object’s toString method Some requirements: Use the Scanner class to do the inputting at the keyboard Set up a Ship class, its two string-type fields, constructor, and toString method Set up a CruiseShip class that extends the Ship class, and it also has its own int-type field, constructor, and toString method Set up a CargoShip class that extends the Ship class, and it also has its own int-type field, constructor, and toString method Set up the main() method as the driver routine in the demo program to create a Ship array whose elements are assigned objects that are instances of Ship, CruiseShip, and CargoShip classes Set up a loop to go through the array elements Having each object’s toString method called for outputting appropriate field(s) Use System.out.print and/or System.out.println to do the outputting

Question

In Java create the following:

Design a Ship class that 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
Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following 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 CruiseShip class’s toString method should display only the ship’s name and the maximum number of passengers
Design a CargoShip class that extends the Ship class. The CargoShip class should have the following 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 CargoShip class’s toString method should display only the ship’s name and the ship’s cargo capacity
Demonstrate the classes in a program that has a Ship array
- Assign various Ship, CruiseShip, and CargoShip objects to the array elements
- The program should then step through the array, calling each object’s toString method

Some requirements:

Use the Scanner class to do the inputting at the keyboard
Set up a Ship class, its two string-type fields, constructor, and toString method
Set up a CruiseShip class that extends the Ship class, and it also has its own int-type field, constructor, and toString method
Set up a CargoShip class that extends the Ship class, and it also has its own int-type field, constructor, and toString method
Set up the main() method as the driver routine in the demo program to create a Ship array whose elements are assigned objects that are instances of Ship, CruiseShip, and CargoShip classes
- Set up a loop to go through the array elements
- Having each object’s toString method called for outputting appropriate field(s)
- Use System.out.print and/or System.out.println to do the outputting
