正在用Java设计一个动漫DRRR中的“罪歌”聊天机器人，想问一下关于代码的问题。
使用System.out是不能无限刷屏的，否则会导致用户无法输入。
输入几个字屏幕就被换行，肯定玩玩。
不过如果是画面形式，当然就无所谓了。
想做一个想小i机器人一样的自动回复程序，用java语言写
ServerSocket ss = null;
Socket socket = ss.accept();
DataOutputStream dos = new DataOutputStream(socket.getOutputStream());//向客户端发送数据的输出流
DataInputStream dis = new DataInputStream(socket.getInputStream());//收客户端发来的数据的输入流
只要接收到的dis.readUTF())值
dos.writeUTF(“自动回复的值”);
JAVA设计一个人工智能的机器人
java机器人游戏最经典的是Robocode项目，里面有详细的文档以及源码，可以自己学习修改。（不要说自己参加这个项目，自己不认真学些东西，那可以面壁了）。下面是它的项目主页
怎么用java开发qq群机器人 服务端 客户端？
