Question

So basically I am trying to fill the array[] element with 9 values, however I am not sure how to get the index within this code. I want it to fill the next element in the array each time.

public boolean check(int data[][], int x, int y){
int array[] = new int[9];
int xmax = x+3;
int ymax = y+3;

        for(int i = x; i<xmax; i++){
            for(int j = y; j<ymax; j++){
                array[] = data[i][j];//array[what here?]
            }
        }
}

Answer 1

for (int i = x; i < xmax; ++i) {
    for (int j = y; j < ymax; ++j) {
        array[3 * (i - x) + (j - y)] = data[i][j];
    }
}
