客户端：

public class TcpClient2 {

public static void main(String[] args) throws Exception{

//获取键盘录入
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
//数据输出给服务器端
OutputStream out=s.getOutputStream();
BufferedWriter bwout=new BufferedWriter(new OutputStreamWriter(out));
//获取服务器端返回的数据
BufferedReader brin=new BufferedReader(new InputStreamReader(s.getInputStream()));
String line=null;
while((line=br.readLine())!=null){
if(line.equals("over"))
break;
bwout.write(line);
bwout.newLine();
bwout.flush();
String str=brin.readLine();
System.out.println("server:"+str);
}
br.close();
s.close();
}

服务器端收到信息后，将信息转为大写返回给客户端。*/
