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();

}

}
