Body
This Piece of code is a part a of a larger project that makes a ti tac toe game for n players on a nxn board, it represents the board of the tic tac toe game. <pre><code>/** represents a tic tac toe board of a given size */ public class TTTBoard { /** 2-dimensional array representing the board * coordinates are counted from top-left (0,0) to bottom-right (size-1, size-1) * board[x][y] == 0 signifies free at position (x,y) * board[x][y] == i for i > 0 signifies that Player i made a move on (x,y) */ private int[][] board; /** size of the (quadratic) board */ private int size; /** This private static integer i used to make a counter */ private static int movecount = 0; /** constructor for creating a copy of the board * not needed in Part 1 - can be viewed as an example */ public TTTBoard(TTTBoard original) { this.size = original.size; for (int y = 0; y < this.size; y++) { for (int x = 0; x < this.size; x++) { this.board[x][y] = original.board[x][y]; } } } /** constructor for creating an empty board for a given number of players */ public TTTBoard(int numPlayers) { this.size = numPlayers+1; this.board = new int[this.getSize()][this.getSize()]; } /** checks whether the board is free at the given position */ public boolean isFree(Coordinate c) { if (board[c.getX()][c.getY()] == 0) { return true; } else { return false; } } /** returns the player that made a move on (x,y) or 0 if the positon is free */ public int getPlayer(Coordinate c) { if (isFree(c) == true){ return board[c.getX()][c.getY()]; }else{ return 0; } } /** record that a given player made a move at the given position * checks that the given positions is on the board * checks that the player number is valid */ public void addMove(Coordinate c, int player) { if (c.checkBoundaries(size, size) == true && isFree(c) == true && player >= 0 && player <= size-1){ board[c.getX()][c.getY()] = player; movecount++; } else { throw new IllegalArgumentException("Ivalid move"); } } /** returns true if, and only if, there are no more free positions on the board */ public boolean checkFull() { if (movecount == size*size) { return true; } else { return false; } } /** returns 0 if no player has won (yet) * otherwise returns the number of the player that has three in a row */ public int checkWinning() { int b = 1; for(int a = 1; a < size-1; a++){ if (board[a][b] == board[a+1][b] && board[a][b] == board[a-1][b]){ return board[a][b]; }else if(board[a][b] == board[a][b+1] && board[a][b] == board[a][b-1]){ return board[a][b]; }else if(board[a][b] == board[a+1][b-1] && board[a][b] == board[a-1][b+1]){ return board[a][b]; }else if(board[a][b] == board[a+1][b+1] && board[a][b] == board[a-1][b-1]){ return board[a][b]; } } for(int a = 1; a < size-1; a++){ if (board[b][a] == board[b+1][a] && board[b][a] == board[b-1][a]){ return board[b][a]; }else if(board[b][a] == board[b][a+1] && board[b][a] == board[b][a-1]){ return board[b][a]; }else if(board[b][a] == board[b+1][a-1] && board[b][a] == board[b-1][a+1]){ return board[b][a]; }else if(board[b][a] == board[b+1][a+1] && board[b][a] == board[b-1][a-1]){ return board[b][a]; } } return 0; } /** getter for size of the board */ public int getSize() { return this.size; } } </code></pre> As my test of running the hole program shows that there are a problem with the addMove, why I know that is because that I get no error massages but the program does not do what I what it too: <pre><code>public void addMove(Coordinate c, int player) { if (c.checkBoundaries(size, size) == true && isFree(c) == true && player >= 0 && player <= size-1){ board[c.getX()][c.getY()] = player; movecount++; } else { throw new IllegalArgumentException("dumpass!"); } } </code></pre> I looks like that the code does not record the moves right, and I cannot see what I do wrong here. x and y coordinates i the board comes from another class Coordinate, and thats why a am using getters to get them.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
