本文一共使用了两个机器人：小黄鸡，小逗比机器人，二者相互调用避免程序出现异常。已经本人调试，完全能用！

第一个（小黄鸡机器人）：

        } else if (sendMsgs.indexOf("Database") != -1
                || sendMsgs.indexOf("Failed") != -1) {
            int random = (int) (Math.random() * 5);
            switch (random) {

                break;

            }
        } else if (sendMsgs.indexOf("Unauthorized access") != -1) {
            sendMsgs = "我怎么听不懂你说的什么意思呀[大哭]。咱们能换个话题吗！";
        } else if (sendMsgs.indexOf("你可以教我回答") != -1) {
            sendMsgs = "好吧";
        }
        // 替换部分内容

        sendMsgs = sendMsgs.replaceAll("小逗比", "小黄鸡");
       
        return sendMsgs;
    }
}

第二个（小逗比机器人）：
