Radius around player (again) sets wrong place

When I do something like this:

Code:

        int x = event.getBlock().getX();
        int y = event.getBlock().getY();
        int z = event.getBlock().getZ();

        int radius = 5;

        System.out.println(x);

        for(x=-radius;x<=radius;x++){
            for(y=-radius;y<=radius;y++){
                for(z=-radius;z<=radius;z++){
                    if(x*x + y*y + z*z > radius*radius)
                    {
                        continue;
                    }
                    if (y>127 || y<0)
                    {
                        continue;
                    }
                    System.out.println(event.getPlayer().getWorld().getBlockAt(x, y, z).getType().toString());
                    break;
                }
            }
        }

x y and z always set to 5 (the radius)

What's wrong with my code? :S

 

I think it is wrong because your saying only continue if y is greater than 127, and less than 0? that doesnt make sense at all? is it supposed to be the other way round?
