Test-Driven Java Development - Second Edition

Implementation

The implementation of this test should be almost the same as the previous one:

private boolean isWin() {
  int playerTotal = lastPlayer * 3;
  for (int i = 0; i < SIZE; i++) {
    if (board[0][i] + board[1][i] + board[2][i] == playerTotal) {
      return true;
    } else if (board[i][0] + board[i][1] + board[i][2] == playerTotal) {
      return true;
    }
  }
  if (board[0][0] + board[1][1] + board[2][2] == playerTotal) {
    return true;
  } else if (board[0][2] + board[1][1] + board[2][0] == playerTotal) {
    return true;
  }
  return false;
}
