This class will represent a Fleet object, which we will define as having:

A name, represented as a String (e.g. United Federation of Planets)

An ArrayList of Starship objects

A constructor which requires all String fields and initializes the collection

A getSizeOfFleet() method which returns the number of starships in the fleet

An addStarship(..) method which takes a Starship parameter and adds it to the fleet, returning nothing.

A toString() method which calls upon the toString() in Starship to return a string representation of the fleet.

Getters and setters for all fields

A loadStarships() method which takes in a directory name and adds a Starship to the Fleet for each file found. This method should not return anything and needs to throw an exception in order to allow for file I/O. To do this you need only define your method as follows: public void loadStarships( String directoryName ) throws FileNotFoundException {
