Simple Proxy Server, Bypassing. Help

I'm creating a simple proxy server that is multi-threaded and will bypass all the host in the host array.
Please help me to my code.

I only want to use socket and streams for this:

Code :

import java.io.*;
import java.net.*;
import java.util.*;
 
public class ProxyServer extends Thread{
 
    private ServerSocket ss;
    private String[] host = {"www.google.com", "www.facebook.com"};
 
    private int remotePort = 80;
    public static long timeout = 30000;
 
    public ProxyServer(ServerSocket server) {
        this.ss = server;
    }
 
    public static void main(String[] args){
        try{
 
            System.out.println("Starting the Proxy Server..");
            ServerSocket ss = new ServerSocket(50005);
            System.out.println("Proxy server started at port " + ss.getLocalPort() + ".\r\n");
            for(int i = 0; i < 5; i++){
                ProxyServer proxy = new ProxyServer(ss);
                proxy.start();
            }
        }catch(Exception e){
            System.out.println(e);
        }
    }
 
    public void run(){
 
        try{
            Socket clientSocket = ss.accept();
            InputStream clientIn = clientSocket.getInputStream();
            OutputStream clientOut = new BufferedOutputStream(clientSocket.getOutputStream());
            for(int i = 0; i < host.length; i++){
                try{
                    Socket serverSocket = new Socket(host[i], remotePort);
                    System.out.println("Open connection to: " + serverSocket + "(timeout= " + timeout + " ms)\r\n");
                    InputStream serverIn = serverSocket.getInputStream();
                    OutputStream serverOut = new BufferedOutputStream(serverSocket.getOutputStream());
                    OpenConnection oc = new OpenConnection(clientIn, serverIn, clientOut, serverOut, clientSocket, serverSocket);
                    oc.run();
                }catch(Exception e){
                    System.out.println(e);
                }       
            }   
        }catch(Exception e){
            System.out.println(e);
        }
    }
}

Code :

import java.io.*;
import java.net.*;
import java.util.*;
 
public class OpenConnection extends Thread{
 
    InputStream clientIn;
    InputStream serverIn;
    OutputStream clientOut;
    OutputStream serverOut;
    Socket clientSocket;
    Socket serverSocket;
    int timeout = 30000;
 
    public OpenConnection(InputStream clientIn, InputStream serverIn, OutputStream clientOut, OutputStream serverOut, Socket c, Socket s) {
        this.clientIn = clientIn;
        this.serverIn = serverIn;
        this.clientOut = clientOut;
        this.serverOut = serverOut;
        this.clientSocket = c;
        this.serverSocket = s;
    }
 
    public void run(){
        int r0 = -1, r1 = -1, ch = -1, i = -1;
        long time0 = new Date().getTime();
        long time1 = new Date().getTime();
        try{
            while(r0 != 0 || r1 != 0 || (time1 - time0) <= timeout) {
                while((r0 = clientIn.available()) > 0) {
                    ch = clientIn.read();
                        if(ch != -1) {
                            serverOut.write(ch);
                            System.out.print((char)ch);
                        }
                    time0 = new Date().getTime();
                    serverOut.flush();
                }
                while((r1 = serverIn.available()) > 0) {
                    try{
                        ch = serverIn.read();
                        if(ch != -1) {
                            clientOut.write(ch);
                        }
                        time0 = new Date().getTime();
                        clientOut.flush();
                    }catch(Exception e){
                    }   
                }
            }
        }catch(Exception e){
            System.out.println(e);
        }finally{
            try{
            clientIn.close();
            clientOut.close();
            serverIn.close();
            serverOut.close();
            clientSocket.close();
            serverSocket.close();
            }catch(Exception e){
                System.out.println(e);
            }
        }
    }
