我想实现服务器和客户端都可以收发信息，不知道哪里错了
package com.jwy.bb;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.net.UnknownHostException;
public class SocketClient {
public static void main(String[] args) {
SocketClient client=new SocketClient();
client.start();
}
public void start(){
Socket socket=null;
BufferedWriter writer=null;
BufferedReader reader=null;
BufferedReader inputReader=null;
try {
socket=new Socket("127.0.0.1",9898);
writer=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
reader=new BufferedReader(new InputStreamReader(socket.getInputStream()));
inputReader=new BufferedReader(new InputStreamReader(System.in));
String inputContent;
String receiveMsg;
while((inputContent=inputReader.readLine())!=null){
writer.write(inputContent+"\n");
writer.flush();
}
while((receiveMsg=reader.readLine())!=null){
System.out.println(receiveMsg);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
try {
inputReader.close();
reader.close();
writer.close();
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
