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 ships 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).

CruiseShip classs toString method should display only the ships name and the maximum number of passengers.

A field for the cargo capacity in tonnage (an int).

In java language.

In the main class, you should read the input file and create an array containing Ship, CargoShip, CruiseShip objects based on the information provided on each line. The file is in CSV (comma separated values) format. This means each line contains multiple data elements separated by comma. You can use Scanner class to input the data or if you know how to work with StringTokenizer you can also use it. Another option is to use the split() method in the String class.

The first column in the file contains the ship type (Ship, CruiseShip, or CargoShip) as a String. The second column contains the Ship Name as a String. The third column contains Year Built as a String. The forth column contains different information for different ship types:

For ship type = Ship - empty (ignore)

For ship type=CargoShip - Cargo Capacity (int)

For ship type=CruiseShip - Max Passengers (int)
