adding certain numbers from multidimensional array
hi, just registered...first post.
first i have this array
Java Code:int secondarray[][]={{0,0,0},{0,0,0},{0,0,0}};
and i was wondering if there is an easier way of writing this code...
Java Code:if(secondarray[0][0]+secondarray[0][1]+secondarray[0][2] == 12  secondarray[1][0]+secondarray[1][1]+secondarray[1][2] == 12  secondarray[2][0]+secondarray[2][1]+secondarray[2][2] == 12  secondarray[0][0]+secondarray[1][0]+secondarray[2][0] == 12  secondarray[0][1]+secondarray[1][1]+secondarray[2][1] == 12  secondarray[0][2]+secondarray[1][2]+secondarray[2][2] == 12  secondarray[0][0]+secondarray[1][1]+secondarray[2][2] == 12  secondarray[0][2]+secondarray[1][1]+secondarray[2][0] == 12){
thanks in advance for any helpLast edited by sirganon; 03292012 at 05:52 PM.

Re: adding certain numbers from multidimensional array
Just to clean things up so others can read your code, you're asking about:
Java Code:if(secondarray[0][0]+secondarray[0][1]+secondarray[0][2] == 12  secondarray[1][0]+secondarray[1][1]+secondarray[1][2] == 12  secondarray[2][0]+secondarray[2][1]+secondarray[2][2] == 12  secondarray[0][0]+secondarray[1][0]+secondarray[2][0] == 12  secondarray[0][1]+secondarray[1][1]+secondarray[2][1] == 12  secondarray[0][2]+secondarray[1][2]+secondarray[2][2] == 12  secondarray[0][0]+secondarray[1][1]+secondarray[2][2] == 12  secondarray[0][2]+secondarray[1][1]+secondarray[2][0] == 12){

Re: adding certain numbers from multidimensional array
sorry and thanks for cleaning that up. ill edit my op too.
im not sure i understand how to use a for loop for this. its a tictactoe game i made and that checks the 8 lines for a win. i just started learning java maybe two weeks ago from youtube videos. while i am understanding some things im not totally aware of all the ways some of these codes can be implemented. could you maybe give an example of how a for loop can be used for this?

Re: adding certain numbers from multidimensional array
Maybe this can be of help: given a cell of your matrix with indexes (x,y); you can 'walk' any straight line through the matrix by repeatedly adding a value (dx, dy) to (x,y); e.g. start at (0,2) and add (1,1) to the index values; the index values are (0,2), (1,1), (2, 0); you have walked over the diagonal from top/right to bottom/left. For suitable values of (x,y) and (dx,dy) you can walk over rows, columns or diagonals. While 'walking' over that line you can register anything you want, given the (x,y) value and m[x,y] value for a matrix m.
kind regards,

Re: adding certain numbers from multidimensional array
ok im still having trouble trying to get JosAH's suggestion working. is there any way i could add it to the code below or should i just keep it separate?
Java Code:public static void display(String x[][]){ for(int row=0; row<x.length; row++){ for(int column=0; column<x[row].length; column++){ System.out.print(x[row][column]+" "); } System.out.println(); } }
