sock_client.java

使用Java编写socket客户端程序的小例子

    import java.io.*;
    import java.net.*;
    public class EchoTest{
    public static void main(String[] args){
     try{
     Socket echoSocket=new Socket("hust",8);
     OutputStream os=echoSocket.getOutputStream();
     DataInputStream is=new DataInputStream
     (echoSocket.getInputStream)());            
     int c;
    String responseLine;
    while((c=System.in.read())!=-1){
       os.write((byte)c);
       if(c==‘\n’){
     os.flush();
     responseLine=is.readLine();
     System.out.println("echo:"+responseLine);
    }
      }
       os.close();
       is.close();
       echoSocket.close();
      }catch(Exception e){
    System.err.println("Exception:"+e);
      }
     }                              
    }
