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.
