Project – Phase II Description
For Phase II, you will save the results of the TicTacToe game to text file. Then you will retrieve these results and perform a statistical analysis on the results. The following are the detailed requirements:
Only the BoardManager will need to be modified;
Use the File, FileWriter, and PrintWriter classes to generate the output file and use the Scanner class to read the file (10 points);
Play 10000 games and write to a text file for each game, the winner of the game or write to the file, that there was a tie; example of the file content (10 points):
O Has Won
X Has Won
Board is Full -- No Winner
O Has Won
O Has Won
Add code to randomly select the player that makes the first selection. Your code should look like this (5 points):
SecureRandom first = new SecureRandom();
double O_or_X = first.nextDouble();
if (O_or_X < 0.5)
{
O selects first
Else
X selects first
}
Read the contents of your saved file and calculate the percent that O won, X won or there was a tie. Your only output should like this (10 points):
Percent O Wins: 46.87
Percent X Wins: 47.11
Percent tie: 6.02
