  以下程序在Jbuilder4下调试成功![下载源程序]
  服务端的程序:
  import java.io.*;
  import java.net.*;
  
  public class SocketServer {
  ServerSocket ss=null;
  Socket s=null;
  DataInputStream inStream=null;
  DataOutputStream outStream=null;
  
  public SocketServer() {
  try{
  init();
  }
  catch(Exception e){
  System.out.PRintln(e.toString());
  }
  }
  
  void init() throws Exception{
  ss=new ServerSocket(765);
  s.setSoTimeout(3000);
  }
  
  void waitForClient(){
  try{
  s=ss.accept();
  inStream=new DataInputStream(s.getInputStream());
  outStream=new DataOutputStream(s.getOutputStream());
  outStream.writeUTF("1");
  s.setSoTimeout(3000);
  waitData();
  }
  catch(Exception e){
  System.out.println(e.toString());
  }
  }
  
  void waitData(){
  while(true){
  try{
  String str=inStream.readUTF();
  System.out.println("Server accept: "+str);
  int nu=Integer.parseInt(str)+1;
  if(nu>20){
  System.out.println("Send end!");
  break;
  }
  else{
  str=Integer.toString(nu);
  outStream.writeUTF(str);
  }
  }
  catch(Exception e){
  System.out.println(e.toString());
  break;
  }
  }
  }
  
  public static void main(String[] args) {
  SocketServer socketServer1 = new SocketServer();
  socketServer1.waitForClient();
  }
  }
  
  客户端的程序:
  
  
  import java.net.*;
  import java.io.*;
  
  public class SocketClient{
  Socket s=null;
  DataInputStream inStream=null;
  DataOutputStream outStream=null;
  
  public SocketClient() {
  try{
  init();
  waitData();
  }
  catch(Exception e){
  System.out.println(e.toString());
  }
  }
  
  void init() throws Exception{
  s=new Socket("192.168.0.32",765); //把这里的ip改成你运行SocketServer.class的IP
  inStream=new DataInputStream(s.getInputStream());
  outStream=new DataOutputStream(s.getOutputStream());
  s.setSoTimeout(3000);
  }
  
  void waitData(){
  while(true){
  try{
  String str=inStream.readUTF();
  System.out.println("Client accept: "+str);
  str=Integer.toString(Integer.parseInt(str)+1);
  outStream.writeUTF(str);
  }
  catch(Exception e){
  System.out.println(e.toString());
  break;
  }
  }
  }
  
  public static void main(String[] args) {
  SocketClient socketClient1 = new SocketClient();
  }
  }
