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");
聊天机器人也就是socket和server,你在他们里边都加上一个线程,互相监听,通过输入和输出流传递信息,然后你从socket端输入一句话,写入流,然后server端读取,处理一下再写入流,然后你socket读取,这就是一个简单的相应了,server端就会等待socket端的下次相应,这太简单了,估计网上不会有这样的教程,你可以大致的参考一下这个思路
