sockets - Getting connection errors while making a server/client chat program in java -

i'm near done project yet i'm trying make sure things working , more client , server connecting, , i'm getting connection errors. here 2 programs. i'm not entirely sure how run both of them @ once in eclipse maybe problem. appreciated

import java.net.*; import java.util.*; import java.io.*;  public class server {    public  void main(string[] args)throws exception {      serversocket server = new serversocket(3333);;      while (true)     {         socket clientsocket = server.accept();         scanner sc = new scanner(clientsocket.getinputstream());         printstream p = new printstream(clientsocket.getoutputstream());         string message = "hello server";         p.print(message);     }  } 

and heres client

    public static void main(string[] args)throws exception {     client display = new client();     display.setvisible(true);      try {     socket server = new socket("localhost", 3333);     scanner sc = new scanner(server.getinputstream());     printstream p = new printstream(server.getoutputstream());     system.out.println(sc.next());      server.close();     sc.close();     p.close();       } catch (unknownhostexception e) {         e.printstacktrace();     } catch (ioexception e) {         e.printstacktrace();     } 

i have gui stuff above , below client didnt show. when run these following errors

java.net.connectexception: connection refused: connect @ java.net.dualstackplainsocketimpl.connect0(native method) @ java.net.dualstackplainsocketimpl.socketconnect(unknown source) @ java.net.abstractplainsocketimpl.doconnect(unknown source) @ java.net.abstractplainsocketimpl.connecttoaddress(unknown source) @ java.net.abstractplainsocketimpl.connect(unknown source) @ java.net.plainsocketimpl.connect(unknown source) @ java.net.sockssocketimpl.connect(unknown source) @ java.net.socket.connect(unknown source) @ java.net.socket.connect(unknown source) @ java.net.socket.<init>(unknown source) @ java.net.socket.<init>(unknown source) @ client.main(client.java:56)
