    Design a class called Ship that has the following members: - Name of the ship-string - Year-the year of the ship built in integer - A constructor, get and set methods - to String that displays the name of the ship and year. Extend a class CruiseShip from Ship with the following members: - Maximum number of passengers - integer - A constructor, get and set methods - To String method that overrides base class to display the name of the ship and number of passengers.

    A and B are any two players in a game which progresses by making alternate moves by the players. Assume the odd moves are played by the player A and the even moves are played by the player B. Define a class for generating the player move which implements runnable interface and ensures that the player is operated with lock. Implement using thread pool so that A and B will get only the alternate moves. The players can stop after making a total of 100 moves.
