Can't figure out when break the loop

4 Aug 2010 by halabella

all links point on this:while((c = is.read()) != -1) { // do something with the response}but this conception seems like wrong, because this loop is ENDLESS, I also tried to send by server "-1" after response - not helped. I confused.[Just trying to receive a response from the server]

Can't figure out when break the loop

4 Aug 2010 by Yusuf

well -1 is not that same as "-1". What are you reading? What does is.read() return when it reaches EOF? that is what you want to look for.

Can't figure out when break the loop

4 Aug 2010 by halabella

What does is.read() return when it reaches EOF?is.read() returns 255 when string was ended, but:- while((c = is.read()) != 255) { // do something with the response}is not a good solution.I think the single way is to transfer by server LENGTH of string, and then, the string.
