    Default Need help with creating Program

    im having trouble with this program assignment that my professor gave us. This is my first semester doing java so im not that good at it yet. Heres the problem...


    For this assignment, your job is to create a kind of lobotomized version of a board game (such as Monopoly) called Opoly.

    Opoly works this way: The board is a straight linear track of variable length (you determine the length when you start up the game). There is only one playing piece, which begins the game just off the board, at position 0. Thus, if the board length is 20, then the board positions start at position 1 and end at position 20. To finish the game, the piece must land exactly on the last cell of the board (e.g., cell 20 in the example above).

    The object of the game is to acquire reward. The reward amount is initialized to 12. If your board piece lands on a board cell that is divisible evenly by 5, your reward doubles. However, if your piece lands one cell shy of the final board cell, your reward is reduced to 1/5 of its current value (via integer division), and your piece must go back to the start position - position 0. Note, though, that if the position of the last cell is divisible evenly by 5, then reward is doubled just before the game ends.

    In Opoly the game piece advances via a spinner - a device that takes on the values 1-2-3-4-5 at random, with each advance value equally likely.

    Two additional rules:

    1) if a spin would move the piece beyond the end of the board, the piece should not advance at all (thus, if the piece is at location 18 of a 20 cell board, and if the spinner spins a 5, this is counted as a move but the piece remains at location 18.) If a piece doesn't move at all, its current reward amount should remain unchanged, even if the piece sits at a location that is divisible evenly by 5.

    2) if the next to last board location is divisible by 5, and if the piece lands on this location, the reward is reduced to 1/5 of its current value only - the reward is NOT also doubled. Example: the board size is 26, and the piece is at location 23, with reward 30. Suppose the spinner spins a 2. This puts the piece on the next to the last location on the board (25). This resets the reward to 6 = 30 * 1/5, and places the piece at location 0. Even though location 25 is divisible by 5, no doubling happens.

    Here is the driver class for the game:
    import java.util.*;

    public class OpolyDriver{

    public static void main(String[] args){
    System.out.println("Enter an int - the size of the board");
    Scanner s = new Scanner(System.in);
    int boardSize = s.nextInt();
    System.out.println("Board Size: " + boardSize);
    Opoly g = new Opoly(boardSize);
    g.playGame();
    }
    }

    Here is a sample run:

    > java OpolyDriver
    Enter an int - the size of the board
    Board Size: 20
    *O****************** 12 // current position is 2, current reward is 12
    ****O*************** 24 // current position is 5, reward is 24
    *******O************ 24
    **************O***** 48
    ********************O 96 // board size is 20, so reward doubles before game ends
    game over
    rounds of play 5
    final reward 96

    A requirement: your Opoly class must include and make use of the following methods, in addition to the Opoly constructor and principal method playGame(). These are:
    * spin - generates a integer value from 1 to 5 at random
    * move - advances the piece
    * spinAndMove - spins the spinner and then advances the piece according to the rules of the game (uses spin, move methods)
    * isGameOver - checks if game termination condition has been met
    * drawBoard - draws the board using *'s and an O to mark the current board position. Feel free to improve on the display we've shown above.
    * displayReport - reports the end of the game, and gives the number of rounds of play, and the final reward



    How to proceed:

    * First, decide on the attributes for the Opoly class. At any instant, what is the "state" of the board? What do you need to keep track of to give the final report? The answers to these questions will tell you what the attributes to Opoly can be.

    * Second, write the Opoly constructor.

    * Third, try to write the playGame method using the methods outlined above. A good way to proceed is to write a "dummy" drawBoard method first - instead of having it draw anything, merely have it print out the current position. Once you're satisfied with the general running of the game in this format, then work on the drawing part.

    * My board rendering is particularly klunky. If you like, you may devise a better way to draw the board. Of course make sure that you get the numbers right.

    Paste in your Opoly class in the box below:

    NOTE: you may NOT use any import statements in your class. Use the Math class methods to generate your random numbers. Do NOT import the java.util library.

    You are at least the third person to post about this particular assignment. Weird.

    Did you read the link I posted? Did you follow the directions in it? If so, you should have some code and a step that you're stuck on. Start there.
