实现网为了提高接单率，可以丰富您的技术顾问资料，展示作品，让充分聘用方充分了解你的工作实力。或者适当调低您的价格，获得好评后再调高价格。这个很不错啊。抽奖算法也很独特。

@junphe 谢谢，成功了，但是第一行每个字段都包含了文件名 temp_training ，比如 temp_training.y_85 ，而我实际上数据库中表的只有 y_85

@c742435 IO 没有满，所以有提升的空间啊，但不知道怎么调

}
public static void main(String[] args) throws Exception {
String source = "火车";//要加密的字符串
System.out.println("要加密的字符串:"+source);
String cryptograph = encrypt(source);//生成的密文
System.out.println("生成的密文:"+cryptograph+"==================");

String target = decrypt(cryptograph);//解密密文
System.out.println("解密密文:"+target+"------------------------");
}
}

@vmebeh 对的，没错，只要包含关键词就行，不管是在字符串首位还是中间还是尾部。

@shoper 不一定的，可以在中间出现，比如大公司，只要能匹配到就是。

@fwrq41251 对，就是想导入 eclipse 修改源代码，怎么做呢

听说spark马上要取代hadoop，所以应该从spark开始学，是这样吧。
