Can't run client/server TCP chat due to java.net.ConnectException
posted 3 years ago
Hello, I'm trying to write a simple client/server TCP chat with Threads but I'm having problems when trying to run some of the codes.
As I'm using Socket, DataOutputStream and BufferedReader, Java makes me write "throws Exception" after each method that uses those objects. On the 'try' field, the object that uses BufferedReader (socketIn, from recieveMsg()) notices there's no one on the other side, listening to the port, and then it throws and exception (java.net.ConnectException).
I tried to use "finally' to execute it without throwing exceptions but I can't use it in the code - I don't know why and I don't know how (Java simply doesn't let me call the method inside 'finally' field). Also, i don't know if I'm using Threads correctly (I wish this part is OK), so I'd like someone's help, if possible, to solve this problem.]
