实现client端功能的clientapp.java原文件：
import java.net.*;
import java.io.*;
import java.lang.*;
public class clientapp
{
public static void main(string args[])
{
try
{
//创建通讯并且和主机rock连接
socket csocket=new socket("192.168.100.188",8018);
//打开这个socket的输入/输出流
outputstream os=csocket.getoutputstream();
datainputstream is=new datainputstream(csocket.getinputstream());
int c;
boolean flag=true;
string responseline;
while(flag)
{
//从标准输入输出接受字符并且写如系统
while((c=system.in.read())!=-1)
{
os.write((byte)c);
if(c=='/n')

//将程序阻塞，直到回答信息被收到后将他们在标准输出上显示出来
responseline=is.readline();
system.out.println("message is:"+responseline);
}
}

os.close();
is.close();
csocket.close();
}
catch(exception e)
{
system.out.println("exception :"+ e.getmessage());
