Answer 1

I think that your code is working the problem is that you are not seeing anything cause what you are writing are not understandable symbols.

Change for (int i = 0; i <=10; i++) { output.write(i); }

for

        for (int i = 66; i <=127; i++) {
            output.write(i);
        }

and tell how it goes.

I hope it helps
