Is this class diagram and program correct for the below prompt? He did not give any expected output or requirement.
Also does the code below meet the following standards?
CODING STANDARDS
All classes should be public
Every class should have a print method
Every class must have a default constructor
Use packages for every lab staring lab 5
all properties (instance or static) should be declared private
class name must start with uppercase
must have public instance methods
main() should be in its own class and can have method for input or for automating testing
one class per .java file
must add a default constructor in each class that is used for creating objects
structure of class
o Instance and static variables
o Constructors
o Instance methods
o Static methods

Exercise 2
Design a Ship, CargoShip and CruiseShip class being mindful of behavior of each. Demonstrate the classes in a program that has a Ship array. Assign various Ships, CruiseShip and CargoShip to the array elements.
CargoShip and CruiseShip are a child of Ship class.

// Assign objects to the array elements.
Ship[] shipArray = new Ship[8];
shipArray[0] = new Ship("USS Typhoon", 2000);
shipArray[1] = new CruiseShip("HMS Queen Victoria", 2001, 200);

shipArray[3] = new Ship("Mustang", 2001);
shipArray[4] = new Ship("Camaro", 2001);
shipArray[5] = new Ship("Muskogee", 2000);
shipArray[6] = new CargoShip("Leviathan", 2006, 100);
