Java board game

Question

Basically I\'m creating a board game in java and have managed to create cells, using arrays, to look like a 10x10 grid. Now I\'ve numbered them they go from left to right t

Ok so I won't write the exact code for you, but I'll show you an example of how to do it with a regular 2D array. I only have a C++ compiler available right now, but it should be clear enough:

So basically you need to cycle through rows from end to start. That's why the first, outer loop you're going from 9 to 0. This will start at bottom row and finish at the top row, thus reversing.

for (int i = 9; i >= 0; i--) {

    // now the trick to making a "zig-zag" is to alternate between two ways
    // of printing out each row. if i is even, you print out from right to left

    if (i % 2)
        for (int j = 9; j >= 0; j--)
            cout << numbers[i][j] << "\t";

    // and if i is odd, you print it out from left to right
    else
        for (int j = 0; j < 10; j++)
            cout << numbers[i][j] << "\t";

    cout << endl;

}

Result:
