网络编程，客户端和服务端间相互发送接受，输出出现方块乱码

Question

package Net;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;

public class UserSocket {
    public static void main(String[] args) throws IOException {
        //连接服务端（ip加端口）
        //连接成功就返回socket对象
        Socket socket = new Socket(InetAddress.getLocalHost(),9999);
        System.out.println("反回了"+socket.getClass());
        OutputStream outputStream = socket.getOutputStream();
        outputStream.write("hello,server".getBytes());
        socket.shutdownOutput();
        InputStream inputStream = socket.getInputStream();
        int readLine=0;
        byte []bytes=new byte[1024];
        while((readLine=inputStream.read())!=-1){
            System.out.println(new String(bytes,0,readLine));
        }
        outputStream.close();
        inputStream.close();
        socket.close();
        System.out.println("客户走了");
    }
}
