Well, I'm calling the constructor with:

result = new Result[rows][cols];

After that, you have a matrix with rows*cols empty cells.

Then you call the constructor for each cell as you are doing with:

for(int p=0;p<32;p++){
for(int q=0;q<32;q++){
result[p][q] = new Result();
}
}

Are you sure the problem is because of that?
