}
//class is used to receive message
class My implements Runnable{
DataInputStream din;
DefaultListModel model;
My(DataInputStream din, DefaultListModel
model){
this.din=din;
this.model=model;
}
public void run(){
String str1=””;
while(true){
try{
str1=din.readUTF(); // receive the
message
// add the message in list box
model.addElement(str1);
}catch(Exception e){}
}
}
}
Server side application
Server side application is used to get the message from any client and broadcast to each
and every client. And this application is also
used to maintain the list of users and broadcast
this list to everyone.
