Ships
Study the UML diagram carefully. The green spots signify public. The red squares signify private. Superclass Ship is abstract because it contains the abstract method purpose. This class also implements the Comparable interface to compare ships by tonnage. Ship also has a public static integer named numShips that is incremented in the constructor to serve as a counter for the number of ships.
After coding these classes, write a program named TestShips that uses them as follows:
⦁ Create an array of declared type Ship that contains at least six ships (two of each concrete subclass). You can make up all of the values for the data members of each ship.
⦁ The Strings returned by purpose() can be determined by viewing the Possible Output below.
⦁ Process the array in an enhanced for loop to display for each ship:
⦁ The actual type using the getClass() method inherited from class Object.
⦁ The output of the toString() method.
⦁ The value returned by the purpose() method.
⦁ Create a Ship arraylist from the array.
⦁ Add one more CruiseShip instance to this arraylist.
⦁ Sort the arraylist by tonnage from low to high.
⦁ Report the value of the static numShips variable.
⦁ Finish up by using an ordinary for loop to run the toString() method of the arraylist elements.
