问题描述

TCPsocket实现一对一通信问题

只需要实现简单的通信，但是服务器没有提示，怎么改
import java.io.*;
import java.net.*;

class Client{
public static void main(String[] args) {
try {
Socket socket = new Socket(""127.0.0.1"" 5050);
DataOutputStream out = new DataOutputStream(socket.getOutputStream());
out.writeUTF(""我是客户机"");//使用UTF-8编码传递字符串
DataInputStream in = new DataInputStream(socket.getInputStream());
String s = in.readUTF();
out.flush();
System.out.println(""客户机收到："" + s);
in.close();
out.close();
socket.close();
}
catch (Exception e) {

    }     }}

服务器端代码

import java.io.*;
import java.net.*;

class Server {
public static void main(String[] args) {
try {
ServerSocket s_socket = new ServerSocket(5050);
Socket socket = s_socket.accept();

        DataInputStream in = new DataInputStream(socket.getInputStream());        DataOutputStream out = new DataOutputStream(socket.getOutputStream());        boolean goon=true;        String s;        while (goon) {        s = in.readUTF();        if (!s.equals(""byte"")) {        System.out.println(""服务器收到："" + s);        out.writeUTF(""我是服务器"");        out.flush();        }        else {        goon=false;        out.writeUTF(""byte"");        out.flush();             }        in.close();        out.close();            s_socket.close();        }        } catch (Exception e) {        }       }}

运行之后没显示

解决方案

我测试了，服务器可以收到数据呀，没问题的
