Question

using Java

In ShipTest:
make two objects with declared type Ship but actual type CruiseShip.
• make one object of declared type Ship but actual type CargoShip.
• make one object of declared type CargoShip and actual type CargoShip.
• make a ship of declared type WarShip and actual type WarShip.
• using the array initializer syntax, code all of these ships into an array of type Ship named fleet.
• code a for loop that processes the fleet array to show display all ships and their data.
• use a method of class Arrays to create an ArrayList of type Ship from the fleet array.
• pass this ArrayList to a method named shipShow that also displays all ships and returns an integer.
report the value of the integer returned by shipShow.
In the shipShow method:
• from the ArrayList, remove the CargoShip that was declared as type Ship.
• add another WarShip instance to the ArrayList.
• use a foreach loop to process the ArrayList and print the data for each ship.
• count the number of ships that are not afloat. Return this count to main for printing.
