To fix that you only need to declare the array as a class member and
inside the run() method you assign the memory to it. Something like:

class Result{
//Data fields...

}
public class Grid2 extends MouseAdapter implements PlugIn {
Result result[][]; // <<<--- I declare it, but it has no memory assigned yet.


public void run(String arg) {
int rows, cols;

// <<<< Here you get matrix size in some way: from a textfield, as a parameter at constructor, or whatever...

result = new Result[rows][cols]; // <<--- Now I assign memory for the matrix


for(int p=0;p<32;p++){
for(int q=0;q<32;q++){
result[p][q] = new Result();
}
}
//*other codes here....which uses This array result[32][32]*
}//*run() ends here*

/*/some other codes that uses result*
}//PlugIn ends here


I hope that helps, but that's not a problem with imageJ, that's plain
java ;)

Sincerelly,
