When you created call[][] then all elements are initailized to null. After creating the array, first thing you need to do it to create a new Cell object and assign it to each element. You can do it as:
for (int i=0;i<size;i++){
for (int j=0;j<size;j++) {
cell[i][j]= new Cell(); // Create and assign new Cell object
}
}
Since hasObstacle is boolean instance variable for Cell object, its value will be set to false by default. So,each cell value for hasObstacle read as
cell[i][j].hasObstacle
will be false after the above for loop is executed.
