Can't figure out when break the loop

Question

1.00/5 (1 vote)

See more:

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]

Solution 1

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.

Solution 2

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.
