[DAS] DAS

[Ethan Cerami]

Also...

If you would rather reader everything in via a buffer,
this also works:

char[] buffer = new char[1000];
while (true) {
   int bytesRead = reader.read(buffer, 0, 1000);
   if (bytesRead == -1) break;
   String str = new String (buffer, 0, bytesRead);
   System.out.println (str);
}
