need to explain this code

hi
this is the most complicated try block i have ever seen
actually i am struggling to understand it
there is a while loop inside another while loop !!!

 try {
                ServerSocket ss= new ServerSocket(2000);
                      while(true){
                        Socket s=ss.accept();
                        connectionCount++;
                        System.out.println("Connection "+connectionCount+" made");
                        is=s.getInputStream();
                        os=s.getOutputStream();
                        pw=new PrintWriter(os,true);
                        br=new BufferedReader(new InputStreamReader(is));
                        System.out.println("System set up");

                        //Read and process names until the client tells the server
                        //the sevice is no longer required.
                        lineRead="";
                        while(true){
                          lineRead=br.readLine();
                          if(lineRead.equals("Exit")) break;
                          o=names.get(lineRead);
                          if(o==null) reply="User not known";
                            else reply=(String)o;
                          pw.println(reply);
                        }
                        pw.close();
                        br.close();
                        is.close();
                        os.close();
                        System.out.println("Closed down");
                      }
                }
                catch(IOException e){
                  System.out.println("Trouble with connection"+e);
                }

The inner while loop condition is set to true. This forces the loop to repeat until a break is encountered. This happens when the BufferedReader reads a line that says 'Exit.'

thank very much
but is it possible to put if action without {}:

if(lineRead.equals("Exit")) break;

but i am still wondering why 2 loops ?
