First paragraph

It says: "For both paramaters, a positive value indicates a clockwise turn; a
negative value indicates a counterclockwise turn."

This is backwards. Positive is counterclockwise; negative is clockwise. The
examples later on the page get it right.

last part of the code on the page

Is written:
int total = dis.readFully(buf);
Have to be:
dis.readFully(buf);
because function readFully() return void.

Beginning with code example at bottom of page

The code on p. 197 calls Connector.open() to create an HttpConnection, then
IMMEDIATELY calls getResponseCode() -- the text in the next paragraph (top of p. 198)
explains that it isn't necessary to first send a GET request because the
"HttpConnection does it for you".

The code on p. 207 calls Connector.open() to create an HttpConnection, then
IMMEDIATELY calls setRequestMethod() to make the request into a POST before it is
sent. BUT HOW WAS THE "AUTOMATIC" SENDING OF A "GET" REQUEST BY THE HttpConnection
SUPPRESSED?

Is it the call to getResponseCode() that actually kicks off the transfer to the
server?
