Objectives: Create a Java program using programming
fundamentals (file I/O, loops, conditional statements, arrays,
functions)
Problem: In an effort to win a coding competition, you decided
to create an awesome Obstacle Warrior game. The game is
played on a 2-dimensional board similar to a Chess board, but
the dimensions may be different. The minimum size of the
board is 2x2. The board will have a Start square and an Exit
square that are not stored on the board. Start and Exit squares
cannot be the same. Other board squares may contain obstacles
in the form of an integer that will define how the warrior
position and score will be affected. The obstacle squares can
have values from 0 to -10 only. The Start square is always a
clear square. All clear squares are marked with # on the board.
The Exit square may contain an obstacle that is not a zero. The
size of the board, number of obstacles, and Start and Exit
squares are all unknow to your code prior to running. This
information is stored in a file that your code will read at the
beginning of the game. The board.dat file must be read into a 2-
D array.
A warrior must start at the Start square and find their way to the
Exit square. The warrior can move on the board in any direction
including diagonally, one square at a time. A warrior has a
running score (integer) maintained from the start of the game
until the warrior exits the board. If the warrior lands on an
obstacle square with a value of zero, the warrior is sent back to
the starting position and the obstacle square will become a
normal square (obstacle removed). If the obstacle square has a
negative number, that number will reduce the warrior's score by
the value of the obstacle, and the obstacle square will become a
clear square (obstacle removed). Each VALID move that the
warrior makes without landing on an obstacle will earn the
warrior one point. The moves for the warrior are randomly

generated by your code in the form of a direction (0-UP, 1-
DOWN, 2-LEFT, 3-RIGHT, 4-UPRIGHT, 5-DOWNRIGHT, 6-
UPLEFT, 7-DOWNLEFT). If the warrior is at the boundary of
the board and your code generates an invalid move, that move
will be ignored. Your code will keep generating moves until the
warrior exits at the Exit square. Once the warrior exits, your
program will store the updated board information to a new file
ResultBoard.dat as single-space separated data. The program
will also display the total number of valid moves, the total time
elapsed in milliseconds since the first move until the warrior
exited the board, the final score of the warrior and the formatted
board information (right aligned columns with total of 5
spaces).
Output Format:
Each column in the final board display must be of total width of
5 spaces
Data in each column must be right aligned
Enter the board data file path: C:board.dat //Repeat prompt
until valid file OR show error and exit.
Type "Start" to start the game or "Exit" to exit the game: exit
//Your program must exit
Enter the board file path: C:board.dat
Type "Start" to start the game or "Exit" to exit the game: start
//You may display the moves and the running score after each
move but it is not required
The warrior made 270 valid moves in 503 milliseconds. The

final score is 175 points.
# # # # #
# # # 0 #
# # # # #
# -3 # # -4
# # # # #
Press any key to exit!
Program Structure: Your code should be modular and easy to
understand. In addition to the main method, the following
methods are required to be in your code. These methods will be
used by the unit testing to test the accuracy of your code.
public static String[][] ReadBoardFromFile(String fileName,
Position startPosition, Position exitPosition)
public static boolean WriteBoardToFile(String fileName,
String[][] boardArray)
public static int GenerateDirection()
public static boolean MoveWarrior(int direction, String[][]
boardArray, Position currentPosition)
public static int CalculateWarriorScore(int currentScore,
Position currentPosition, String[][] boardArray)

public static String DisplayResults(int currentScore, int
numberOfMoves, int timeElapsed, String[][] boardArray)
Program Flow:
Program starts in main() method
Prompt user for Board.dat file path
Read board from file
Generate a direction
Move the warrior
Calculate new score
Check conditions and clear square if needed
Repeat until the warrior is at the exit square
Display the results
Prompt user to exit game
Board.dat file format:
The data in the file will be separated by one space
Assume that all data in the file is valid
Clear and Start squares (no obstacles) will be marked with # in

the file
The first line of the file contains the dimensions of the board
(rows and columns) e.g. 3 7
The second line contains the Start square indexes (rowIndex,
columnIndex)
The third line contains the Exit square indexes (rowIndex,
columnIndex)
The rest of the lines represent the contents, including obstacles,
of a row on the board
Example of a Board size 5x5 data file:
5 5
2 2
4 3
# -5 # # #
# # # 0 #
# # # # #
# -3 # # -4
-10 # # # #
**ResultBoard.dat file format: **

Data must be separated by a single space
# # # # #
# # # 0 #
# # # # #
# -3 # # -4
# # # # #
Grading:

above (10 Points)
ReadBoardFromFile (10 Points)
WriteBoardToFile (10 Points)
GenerateDirection (10 Points)
