这是第二段:
import java.net.*;
import java.io.*;
public class ReverseClient {
public static void main( String[ ] args ) {
if ( args.length < 1 ) {
System.err.println( "ReverseClient <IP address of server>" );
return;
}
try {
String s = "In the Quiet Morning";
Socket sock = new Socket( args[ 0 ], 1234 );
PrintWriter out = new PrintWriter( sock.getOutputStream() );
out.println( s );
out.flush();
BufferedReader in = new BufferedReader(
new InputStreamReader( sock.getInputStream() ) );
String t = in.readLine();
if ( t != null )
System.out.println( "To server: " + s +
"\nFrom server: " + t );
sock.close();
} catch( IOException e ) { System.err.println( e ); }
}
}
要考试了,请各位高手帮帮忙,先谢了~~

用Socket进行远程数据接收。

[hq1305018]

public class Reverse {
public static void main( String args[ ] ) {
ServerSocket sSock = null;//服务器端套接字
try {
sSock = new ServerSocket( 1234 );//服务端口为1234
}
catch( IOException e ) {
System.err.println( e ); //有错误输出异常信息并返回。
return;
}
System.out.println( "Server running..." );//打印"Server running...."
while ( true ) {//循环接收客户端请求
try {
Socket sock = sSock.accept(); //接收到客户端请求，建立服务套接字。
BufferedReader in = new BufferedReader(
new InputStreamReader( sock.getInputStream() ) );//获取输入流
String t = in.readLine();//获取消息(从客户端);
if ( t != null ) { // something read?如果有消息
PrintWriter ps = new PrintWriter(sock.getOutputStream());//建立输出流
ps.println(new String(new StringBuffer(t).reverse()));//将消息字符串转置。
ps.flush();//刷新缓存
}
sock.close();//关闭套接字
} catch( IOException e ) { System.err.println( e ); }//操作异常打印异常信息。
}
}
}

大哥,我要的是详细的注释啊,

[stonecsdn]

public class Reverse {
public static void main( String args[ ] ) {
ServerSocket sSock = null;
try {
sSock = new ServerSocket( 1234 );//生成一个服务器端的socket，端口号1234
}
catch( IOException e ) { //异常返回
System.err.println( e );
return;
}
System.out.println( "Server running..." );
while ( true ) {//循环接受数据
try {
Socket sock = sSock.accept();//生成一个服务器端用来于客户端交互的 //socket，前提是有客户端访问
//

BufferedReader in = new BufferedReader( //
new InputStreamReader( sock.getInputStream() ) );
String t = in.readLine();
if ( t != null ) { // something read?
PrintWriter ps = new PrintWriter(sock.getOutputStream());
ps.println(new String(new StringBuffer(t).reverse()));
ps.flush();
}
sock.close();
} catch( IOException e ) { System.err.println( e ); }
}
}
}

[camel4057]

public class Reverse { //你的类名
public static void main( String args[ ] ) { //主函数入口
ServerSocket sSock = null; //定义一个服务器端的socket
try {
sSock = new ServerSocket( 1234 ); //将sSock在1234端口处实例化
}
catch( IOException e ) { //异常处理
System.err.println( e );
return;
}
System.out.println( "Server running..." ); //输出Server running....
while ( true ) { //服务端一直执行，直到用户中断
try {
Socket sock = sSock.accept(); //建立一个soket来接受服务器端收到的数据。
BufferedReader in = new BufferedReader( //建立一个bufferedReader对象，用来存放接收到的数据。
new InputStreamReader( sock.getInputStream() ) );
String t = in.readLine(); //一行一行的读取数据
if ( t != null ) { // something read? //如果用数据，就把数据显示出来。
PrintWriter ps = new PrintWriter(sock.getOutputStream());
ps.println(new String(new StringBuffer(t).reverse()));
ps.flush();
}
sock.close(); //关闭socket对象
} catch( IOException e ) { System.err.println( e ); }//异常处理
}
}
}

还有第二段,请高手帮帮忙,也注释一下

[hq1305018]

这是第二段:
import java.net.*;
import java.io.*;
public class ReverseClient {//客户端类
public static void main( String[ ] args ) {
if ( args.length < 1 ) {//如果没有参数，打印使用说明,并返回。
System.err.println( "ReverseClient <IP address of server>" );
return;
}
try {
String s = "In the Quiet Morning";//要发送的初始消息。
Socket sock = new Socket( args[ 0 ], 1234 );//建立客户端套接字。
PrintWriter out = new PrintWriter( sock.getOutputStream() );//建立输出流。
out.println( s );//向服务器端发送消息
out.flush();//刷新缓存
BufferedReader in = new BufferedReader(
new InputStreamReader( sock.getInputStream() ) );//建立输入流。
String t = in.readLine();//读取服务器端消息。
if ( t != null ) //如果消息不为空，打印发出的消息和接收到的消息。
System.out.println( "To server: " + s +
"\nFrom server: " + t );
sock.close();//关闭套接字。
} catch( IOException e ) { System.err.println( e ); }//操作异常，打印异常信息。
}
}

那个通信的程序没有指定Server的IP怎么能联上去？请高手指点一下。
