FileOutputStream - sometime writing data and sometime not

I am trying to understand few java file concepts. So I tried with below program to understand FileOutputStream

FileOutputStream out = new FileOutputStream("test.txt");
int i = 1;
out.write(i);
out.flush();
out.close();

Some binary data has been writen in the file.

But the for the same program when I change the value of i from 1 to 10. I don't see anything in my output file. Can someone explain me why with some internal details.

int i = 1;
out.write(i);

That writes 0x1 to the file.

out.flush();
out.close();

The flush() is redundant.

Some binary data has been writen in the file.

Correct.

But the for the same program when I change the value of i from 1 to 10. I don't see anything in my output file.

Yes you do. You see 0xa, which is a line feed character.
