我写了一个与telnet一起使用的聊天服务器。我写了一个连接到服务器的客户端。在终端中，我通过给它提供文件的名称以及IP地址和端口来运行客户端。它似乎连接，因为它关闭服务器并发生以下错误：

我的聊天服务器代码是：
import java.io.*;
import java.util.*;
import java.net.*;
import static java.lang.System.out;
public class ChatServer {

ArrayList<String> buffer = new ArrayList<String>();

}
try{
client.close();
}
catch(Exception e) {
System.out.println(e.getMessage());
}
} // end of run()
} // end of inner class
}
我的客户代码是：
public class ChatClient {
PrintWriter output;
BufferedReader input;
Socket client;
public ChatClient(String ip, int port) throws Exception {
client = new Socket(ip,port);
input = new BufferedReader( new InputStreamReader( client.getInputStream()) ) ;
output = new PrintWriter(client.getOutputStream(),true);
}
public static void main(String args[]) {
try {
String ip= args[0];
int port= Integer.parseInt(args[1]);
new ChatClient(ip,port);
} catch(Exception ex) {
out.println( "Error --> " + ex.getMessage());
}
} // end of main
答案 0 :(得分：0)
添加
input.readLine();
到您的ChatClient类
