testing tic tac toe win condition

testing tic tac toe win condition

I'm looking for the most efficient java way to test if somebody has won at
tic tac toe. The data is in a 2d array like so...
char[][] ticTacToe =
{{'X',' ','O'},
{'O','X','O'},
{'X',' ','X'},};
I know this isn't the professional way to initialize an array but I'm just
testing here.
The best I can do for right now is an exhaustive if/else tree. Here's one
of those trees...
if (ticTacToe[1][1] == 'X'){
if (ticTacToe[0][0] == 'X'){
if (ticTacToe[2][2] == 'X'){
System.out.println("X wins");
}
}
else if (ticTacToe[0][1] == 'X'){
if (ticTacToe[2][1] == 'X'){
System.out.println("X wins");
}
}
else if (ticTacToe[1][0] == 'X'){
if (ticTacToe[1][2] == 'X'){
System.out.println("X wins");
}
}
else if (ticTacToe[2][0] == 'X'){
if (ticTacToe[0][2] == 'X'){
System.out.println("X wins");
}
}
}
This one only cares about what's in the middle
This is very basic and I want to improve it as far as minimizing lines of
code goes.
