Once the application starts you have two choices: create server or join server. They way I intend to do it is the following: If (typedMessage != null & typedMessage.I just got started with socket programming so in order to improve my understandings of it I wanna build a multi-client chat application. String typedMessage = inputReader.readLine() tPriority(Thread.MAX_PRIORITY) īufferedReader inputReader = new BufferedReader(new InputStreamReader(System.in))
String recvedMessage = new String(arrayBytes, "UTF-8") System.arraycopy(readBuffer, 0, arrayBytes, 0, num) ServerSocket serverSocket = new ServerSocket(3339) One thread is for reading from the socket and the other is writing to socket.If the connection is terminated from client side, the server also exits. The ChatSocketServer.java is the server application.It simply creates a serverSocket on port 3339.Once a new connection comes, it accepts that connection and Socket object will be created for that connection.Now two threads will be created.
We have a server as well as a client.Both can be run in the same machine or different machines.If both are running in the machine, the adress to be given at the client side is local host address.If both are running in different machines, then in the client side we need to specify the ip address of machine in which server application is running. In this chapter we are discussing a console based(no GUI for this application) chat application in Java Chat application in Java Examples on TCP communication and UDP communication were also discussed. So far we discussed about socket communication principles.
