Hi,
i want to implement a client /server codes in the following fashion :
the client A should enter the IP of of the server and clients B and C enters the same IP,so the three clients can communication with each other through the server.
The server could omit any client from the service.
any good tutorials or examples?
I appreciate any help.
thanks so much,but still have one problem
how can i remove a specific client from the server by entering the client IP?
That question is so far out of context as to be unanswerable. If you wish your question answered, then I recommend providing more contextQuote:

and if you have a list of clients' with their status and data such as their IP,
then you could have a method that searches the list and removes the client based on their IP.
and how to create such a list and close the connection with a client from that list?Quote:

please, i need some code examples ,i appreciate that.
Post your code so we can see where and how you are getting and saving the necessary information about the connections
I guess I stand corrected.Quote:

this is the server code.i didn't write all the code but i modified it
so i can get the IP of all the clients in the Begin thread by the getInetAddress() method,(that's how i can create a list of the clients define them by IP when i switch to GUI)Code:
public class sender {
ServerSocket MyService;
BufferedInputStream input;
TargetDataLine targetDataLine;
BufferedOutputStream out;
ByteArrayOutputStream byteArrayOutputStream;
AudioFormat audioFormat;
SourceDataLine sourceDataLine;
byte tempBuffer[] = new byte[10000];
sender() throws LineUnavailableException{
try {
audioFormat = getAudioFormat();
DataLine.Info dataLineInfo = new DataLine.Info( SourceDataLine.class,audioFormat);
sourceDataLine = (SourceDataLine)
AudioSystem.getLine(dataLineInfo);
sourceDataLine.open(audioFormat);
sourceDataLine.start();
MyService = new ServerSocket(500);
} catch (IOException e) {
e.printStackTrace();
}
try{
while(true){
new Begin(MyService.accept()).start();
MyService.close();
}
}
catch(Exception e){
System.out.println(e);
}
}
private AudioFormat getAudioFormat(){
float sampleRate = 8000.0F;
int sampleSizeInBits = 16;
int channels = 1;
boolean signed = true;
boolean bigEndian = false;
return new AudioFormat(
sampleRate,
sampleSizeInBits,
channels,
signed,
bigEndian);
}
public static void main(String s[]) throws LineUnavailableException{
sender s2=new sender();
}
private void captureAudio() {
try {
Mixer.Info[] mixerInfo = AudioSystem.getMixerInfo();
audioFormat = getAudioFormat();
DataLine.Info dataLineInfo = new DataLine.Info(
TargetDataLine.class, audioFormat);
Mixer mixer = AudioSystem.getMixer(mixerInfo[2]);
targetDataLine = (TargetDataLine) mixer.getLine(dataLineInfo);
targetDataLine.open(audioFormat);
targetDataLine.start();
Thread captureThread = new CaptureThread();
captureThread.start();
} catch (Exception e) {
System.out.println(e);
System.exit(0);
}
}
class CaptureThread extends Thread {
byte tempBuffer[] = new byte[10000];
public void run() {
try {
while (true) {
int cnt = targetDataLine.read(tempBuffer, 0,
tempBuffer.length);
out.write(tempBuffer);
}
} catch (Exception e) {
System.out.println(e);
System.exit(0);
}
}
}
class Begin extends Thread{
private Socket clientSocket;
public Begin(Socket sock){
this.clientSocket=sock;
System.out.println(clientSocket.getInetAddress());
}
public void run(){
try{
captureAudio();
input = new BufferedInputStream(clientSocket.getInputStream());
out=new BufferedOutputStream(clientSocket.getOutputStream());
while(input.read(tempBuffer)!=-1){
sourceDataLine.write(tempBuffer,0,10000);
}
}
catch(Exception e){
System.out.println(e);
System.exit(0);
}
}
}
}
Let us say I have a button (Remove),when i click Remove an input dialog would appear and i should write the IP of the client that i want to remove him
from the server.How to close the connection with that client without affect the other clients communication?
Change the code so that the socket is saved in a list before passing the socket to the Begin class.
