Network programming while loop and read method, network programming whileread

 

 

Different from the file input stream, the input stream in network programming does not know whether there will be data transmission on the other side. Even if the data transmission is complete, the program will continue to wait for data transmission on the other side, at this time, if you write the condition in the while loop! =-1, it will die in the loop, because it will wait for the other side to continue to transmit data.
