java - my proxy server doesn't work as expected -

i developed simple, multi-threaded proxy server. note program proxy 1 specific server. here code :

    public class proxy {      int remoteport;     inetaddress remotehost;      public proxy(inetaddress remotehost, int remoteport) {         this.remoteport = remoteport;         this.remotehost = remotehost;     }      public void go() {         executorservice pool = executors.newcachedthreadpool();         try (serversocket server = new serversocket(2015);) {             system.out.println("proxy running....!");             while (true) {                 socket socketclient = server.accept();                 system.out.println("client connected...!");                 socket socketserver = new socket(remotehost, remoteport);                 system.out.println("connection established server...!");                 worker p1 = new worker(socketclient, socketserver);                 worker p2 = new worker(socketserver, socketclient);                 pool.execute(p1);                 pool.execute(p2);              }         } catch (exception ex) {             system.out.println(ex.getmessage());         }      }      class worker implements runnable {          socket from, to;          public worker(socket from, socket to) {             this.from = from;             this.to = to;         }          @override         public void run() {             system.out.println(thread.currentthread().getname());             try (bufferedinputstream bis = new bufferedinputstream(from.getinputstream());                     bufferedoutputstream bos = new bufferedoutputstream(to.getoutputstream());) {                 while (true) {                     int octet = bis.read();                     if (octet == -1) {                         break;                     }                     bos.write(octet);                  }                 bos.flush();                 from.close();                 to.close();             } catch (ioexception ex) {                 system.out.println(ex.getmessage());             }          }      }      public static void main(string[] args) {         inetaddress adr = null;         try {             adr = inetaddress.getlocalhost();         } catch (unknownhostexception ex) {             system.out.println(ex.getmessage());         }         new proxy(adr, 2020).go();     }  } 

i test proxy server client , server. client sends array of integers find maximum. server of turn, returns maximum of received array. problem following: proxy server not playing role. array not sent server , client not received maximum value of array. code of server follow:

    public class servertcpmax {      static void display(int[] tab) {         (int u : tab) {             system.out.print(u + " ");         }         system.out.println();      }      static int searchmax(int[] t) {         int max = t[0];         (int = 1; < t.length; i++) {             if (t[i] > max) {                 max = t[i];             }         }         return max;     }      public static void main(string[] args) {         try {             serversocket server = new serversocket(2020);             system.out.println("server running .......!  ");             while (true) {                 try (socket sclient = server.accept()) {                     system.out.println("proxy connected...!");                     objectinputstream ois = new objectinputstream(sclient.getinputstream());                     int[] tab = (int[]) ois.readobject();                     display(tab);                     int max = searchmax(tab);                     try (dataoutputstream dos = new dataoutputstream(sclient.getoutputstream())) {                         dos.writeint(max);                         dos.flush();                      }                 }             }         } catch (ioexception | classnotfoundexception ex) {             system.out.println(ex.getmessage());         }     }  } 

the following code represents client:

 public class clienttcpmax {      public static void main(string[] args) {         int[] = {3, -7, 9, 22, 0, 7, 11, 2};         try {             try (socket socket = new socket("127.0.0.1", 2015)) {                 system.out.println("connection established proxy ...!");                 objectoutputstream oos = new objectoutputstream(socket.getoutputstream());                 oos.writeobject(a);                 oos.flush();                 datainputstream dis = new datainputstream(socket.getinputstream());                 int max = dis.readint();                 system.out.println(" max : " + max);             }         } catch (ioexception ex) {             system.out.println(ex.getmessage());         }     } }
