JAVA网络编程

[hcyjsj86]

大家好，我刚开始学习JAVA网络编程，请问哪位高手可以把下面的这个服务器端程序和客户端程序的注释详细的写一下给我啊，谢谢了！

服务器端：
import java.io.*;
import java.net.*;
import java.applet.Applet;
public class ServerSocketTest{
public static void main(String args[]){
try{
ServerSocket socketObj = null;
try{
socketObj = new ServerSocket(4700);
}catch(Exception e){
System.out.println("There is a connetion error");
}
Socket clientObj = null;
try{
clientObj = socketObj.accept();
}catch(Exception e){
System.out.println("Error:"+e);
}
String strLine;
InputStreamReader streamObj1 = new InputStreamReader(clientObj.getInputStream());
BufferedReader buffObj1 = new BufferedReader(streamObj1);
OutputStream outObj= new BufferedOutputStream(clientObj.getOutputStream());
PrintWriter writerObj = new PrintWriter(outObj);
InputStreamReader streamObj2 = new InputStreamReader(System.in);
BufferedReader buffObj2 = new BufferedReader(streamObj2);
System.out.println("Client words:"+buffObj1.readLine());
strLine = buffObj2.readLine();
while(!strLine.equals("Finished"))
{
writerObj.println(strLine);
writerObj.flush();
System.out.println("Server words:"+strLine);
System.out.println("Client words:"+buffObj1.readLine());
strLine = buffObj2.readLine();
}
buffObj1.close();
writerObj.close();
clientObj.close();
socketObj.close();
}catch(Exception e){
System.out.println("Error:"+e);
}
}
}

客户端：
import java.io.*;
import java.net.*;
public class ClientSocketTest{
public static void main(String args[]){
try{
Socket socketObj = new Socket("127.0.0.1",4700);
InputStreamReader instreamObj=new InputStreamReader(System.in);
BufferedReader buffObj1=new BufferedReader(instreamObj);
OutputStream outstreamObj=socketObj.getOutputStream();
PrintWriter writerObj=new PrintWriter(outstreamObj);
InputStream inputObj=socketObj.getInputStream();
InputStreamReader instreamObj2=new InputStreamReader(inputObj);
BufferedReader buffObj2=new BufferedReader(instreamObj2);
String strLine;
strLine = buffObj1.readLine();
while(!strLine.equals("Finished"))
{
writerObj.println(strLine);
writerObj.flush();
System.out.println("Client words:"+strLine);
System.out.println("Server words:"+buffObj2.readLine());
strLine = buffObj1.readLine();
}
writerObj.close();
buffObj2.close();
socketObj.close();
}catch(IOException e){
System.out.println("IO error");
}
}
}

你随便找一本书看看应该就明白了啊

try{
ServerSocket socketObj = null;
try{
socketObj = new ServerSocket(4700);//建立服务器端套接字
}catch(Exception e){
System.out.println("There is a connetion error");
}
Socket clientObj = null;
try{
clientObj = socketObj.accept();//监听直到收到客服端请求
}catch(Exception e){
System.out.println("Error:"+e);
}

//下面就是做一些工作后就可以用strLine = buffObj2.readLine()取数据了，没看懂为啥子你要这么用
InputStreamReader streamObj1 = new InputStreamReader(clientObj.getInputStream());
BufferedReader buffObj1 = new BufferedReader(streamObj1);
OutputStream outObj= new BufferedOutputStream(clientObj.getOutputStream());
PrintWriter writerObj = new PrintWriter(outObj);
InputStreamReader streamObj2 = new InputStreamReader(System.in);
BufferedReader buffObj2 = new BufferedReader(streamObj2);
//直到接收到Finished后才退出，关闭套接字
while(!strLine.equals("Finished"))
{
writerObj.println(strLine);//往客户端发送数据
writerObj.flush();
System.out.println("Server words:"+strLine);
System.out.println("Client words:"+buffObj1.readLine());
strLine = buffObj2.readLine();
}




客服端差不多就部说了，建议看看书 ，那个发送和接收数据用不着搞得怎么麻烦得
