完整有效的profile数据: 可是为啥点rec就变数了？
蛋白棒：柱形图的比例不对，表格里两个size也不对
年龄-20存档的时候要保持红色，
valid文件打开后没有3 products found， 怎么打开啊？search的时候是239089条记录
我自己写的感觉比较原生态，完全没有exception。加exception感觉会加的差不多。能改变思路么？空-有效性，好像不能改啊。变量的顺序甚至都不好改……。判断是不是数字的办法只有把它转为float的时候失败才算吗？不是吧

为啥profile营养数量有错检测不出来啊？！
case
console不能报错
- new profile
输入三个变量以后aclevel自动变成secondary，自动生成推荐营养。后面的改动也会导致自动变化。
- search
输入一个product，搜出结果来。指定有protein的：结果更少。指定有ingredient的：结果更少。clear之后左下全部清零。
全为0时点search，出现43个产品。vitamin a + salt = 12 + olive oil = 1
- add
protein bar - 2 - add - 出结果， 百分比 = actual / recm * 100%，输入size后，hoseholdsize 随即变化
remove product from diet 柱子随即减少，左边的推荐营养不减少
- save
加两个产品，然后save，存一个新的CSV文件名 APP内部点close，内部open存了的那个文件，恢复原来的数据
- Exception handling in profile user input
age twenty红字，退格后回到黑字，三个变量都要
- rec exception
输入不对的时候，红框指出第一个发生的错误。注意下：没有事missing，格式不对是incorrect。-30：must be a positive number。
三个变量都对之后，立马动态产生推荐营养。
- profile exception
打开那个valid的文件：注意下，4个大框全都有数。
missing gender - 红框（记得改一下提示语句） - 注意下，然后还有一个红框！（此时后面的背景都是空的）
only person：第一个大框里有数。close以后回到盘子界面。
- product exception
无效product number - 红框（记得改一下提示语句）- 四个框全有数 -
无效quantity - 只有第一个大框里有数 - OK以后4个大框里全有数，回到原来值 - close后回到盘子界面
- save exception
不给gender就save 出红框。missing 三个变量也出红框。注意下，变量输入错误还是红字。负数还是红框提示positive。
- 大文件exception
打开validate全能文件 - remove所有product - 柱形图消失 -
clear search - 区域2消失 - 点击search - 等一阵 - 出现239089个product -
搜索bread protein chocolate，出现85个产品，添加一个大老鹰面包
clear
搜索名为NATURE的产品，因为serving size是0所以柱形图不动，
搜索TRADITIONAL GREEK YOUGURT，因为househoudesize = 0，serving size不等于，所以柱形图会动
list.get(0) = CSVRecord [comment=null, mapping=null, recordNumber=1, values=[Female, 25, 55, 160, 1.48, chocolate, peanut]]怎么用这个来新建person啊
-------总之就是controller有问题
【问题1：new以后有问题，不知道怎么处理】
检查一下空文件的效果: 【问题2：不对，应该出两个框，这里只出了一个】
【问题3：test case飘红，看得我急死了】
【问题1】
populateDietNutrientMap里的RecommendedNutrient是从哪里取出来的啊？AddDietButtonHandler的也要存吗？
先从pn里面拿code和名字，再存一遍
说是对的，没有清单吗不过？
唉不想写了，自己写什么都不会，没人讨论，完全是在虚度。算了，先写数据库吧hhh。

【search function】
怎么写啊我去，先看视频吧还是。看懂了，for循环吗？之前有例子吗？没有诶，自己写两句吧。
是从model里拿和放东西，好吧。可是输入的字符串是哪里来的啊？
【save memu】
看上去好复杂啊，完全不会啊，妈的。好想直接复制粘贴……真是太复杂了，自己瞎写肯定写不出来。先看看视频8。
那就从FC先开始写好咯？person要处理exception 然后用CSV Write
感觉写不出来完全就是在浪费时间，但是吧，不写几个字又不甘心。还是算了吧，自己瞎写不如抱大腿。
【openmenu】
好像挺麻烦的呢，唉。好像要打开、计算？啥意思啊，我去。 加exception？这里怎么加啊，之前的都写不对，唉，我去。该不该先把之前的搞对再说哦？
后面的几个handler都和shit一样啊，妈的。
再看看内俩案例吧。处理输入输出数字的exception和处理文件的，应该不一样8？真不一样，还是看看课件8
课件里都是处理数字输入的exception啊，并不是读文件，但是都是把错误的语句放在try中
所以应该是判断文件非空吧，我觉得。应该是的，不过不知道应该往哪里输出，要看看以前的menu往哪里输出吧，我觉得。就是推荐营养那里。所以在哪里打印异常呢？再看看视频。就是和CSVFILER一样，4个变量都要处理，输出到红框框里，不过我真没有找到红框框的view在哪里啊。而且不是说是判断文件的异常吗，怎么视频里就要判断输入输出的异常了呢？哦，这是【recommendednutrient】，一样的道理，那就先不写吧。
【newmenu】
怎么往newmenu里面加chart啊，我去，应该和list类似吧？实例给view了？我咋没看见呢。看见了。不过要clear哪些东西啊，还要添加配置么。 view好像都没变的，就不用再controller里面新建了吧。那new就先这样。
清理chart好像直接用就行了8，不过我为了保险起见还是把它的几个list都清理掉了。
【我在写exception】
validate product这个，读到下一行，是什么鬼。怎么换行啊，用n吗。不论怎么分隔，好像和我之前的结果一样，是什么鬼。 那就随意咯？先用n来写好了。然后用iter? 不让我用是咋回事，傻逼吧。必须要list， 数组不行。那就先加到list里面咯？可以了哈哈哈。
先不写，跑跑效果试一试。好吧，不写果然没有exception，天下没有免费的exception，好吧hhh.
validateProduct应该只要管product就好了吧
如果全是空的，反而没有exception了，是这个意思吗？
突然想试试case了，看是哪里不过……不能建立nurtibyte是什么鬼阿。先修修这类吧？好像是因为exception，那就写exception先咯。可是我exception写不对啊……先试试吧
productNUMBER找不到是啥意思啊，去哪里找？好像是productMap
写错了，没有catch到。。不会。。。5555
感觉我这想法不是特别对，算了，明天问问助教
下午写界面，然后看看
【问题1】
exception就是不知道怎么打印到小框框Field里，没找到.
范围是什么啊？还是自己瞎编就行啊。发现missing gender也没写诶，性别是第0位吗 究竟还是身高？性别，好吧
我需要看看视频中的正确提示语句再写. 怎么感觉视频里的界面更复杂？我去，再看看。发现下面一行字应该在exception括号里。
那括号里为啥还要嵌入数据啊我去……用加号就行，好吧。
原来only person而没有产品的时候不会throw exception，好吧。
好，这个exception差不多就这样吧，看看界面怎么搞出来。就是上面4个变量都要判断，不对就显示红框框，和CSVFiler一样不会，不知道红框框在哪里啊。
自己写的错filer

为啥有红字：没catch，让我去model里面catch，也不对吧？而且完全没思路，一点也不会啊
【问题2】
product exception我的思路是不是有问题啊，怎么识别不出来
然后product全都没有的话就展示第一个人，是神马意思
【save menu完全不会阿】要根据前面的来写
【问题3】
ProductComboBoxListener怎么写啊，什么意思都不懂，所以model就不会
提示了一个新的handler 还没写
【model里的filewrite怎么写啊，所以CSV里的write也不会】
model的wrtite怎么写啊？是不是要看XML 不是，是一个统一的。要用到哪个知识啊？pdf或者别的文件里有吗
有的，用buffer
发现write profile 和write file是分开的， 先写CSVFILER里面的吧，更具体。filename是括号里的东西。
具体存了多少数啊？？profile and diet products data是一些啥？应该是profile和diet products分开吧，所以要写两次
用S分割是代表一行数据吧， 存profile，那就是5个咯
仔细看图，发现model用了Data filer，那就看看filer咯。原来是实现接口，好吧。所以照抄，一样的。为啥Case过不了啊，奇怪。哦，写没法测试，那就再说吧。
exception好像能写8 看老师给的
不知道读的表格在哪里啊，先看看Exception怎么写再说8
怎么有的是内部类，有的是boolean啊什么鬼，到底信谁。应该是类里面写方法。没有那个方法啊可是，看来不对。
直接try catch试试？
是验证string啊，但是打印不出来，那就先随便写吧。也不知道应该用什么分隔符,写的s+不知道对不对
数据范围也忘了，还得回去看HW2，我日
不知道exception要打印在哪啊，先试试console上好了, 猪啊，怎么还是case过不去啊我日
哦，应该打开，可是打不开，我日，修好了
format exception？看来果然读错了 。哈哈哈哈哈，没读错，就是不知道怎么打印到小框框Field里，没找到。哈哈哈哈哈哈哈哈。所以继续写完。
好难受啊，编不下去了，听歌试试？好像还蛮舒服的诶
还有几个变量的exception没写完，
【主要是前面指定有错，newmenuhamdler里怎么清理chart啊】
【savemenu怎么写啊 搜一下吧先】
【searchbotton怎么写啊 搜一下吧先】
【clearhbotton怎么写啊 搜一下吧先】
。。。
两个写好像还不一样啊？？一人一个
发现很多handler没写，难受
不知道怎么改person，看看图吧
于是开始写controller了，主要部分
可是还是从头往后写吧，不会的先空着
static是类的，non-static是一个实例化变量的，这基本概念了吧，赶紧复习。
我想要populate一个map,它却有两个输入是咋回事，我去。看了一下计算，能给我气吐血。我的耐心已经耗尽……于此。妈蛋，map里存的是什么啊。好像存的是两个servingsize的比例? 还是product， nutrient？怎么把产品的营养取出来啊，存在哪里了啊？我觉得是在productnutrient里, 我看看。product类里面的nutrient?有啥联系么。突然发现是Recommendednutrient，唉算了。先从product里拿出来，再存到person里面去吧？我怎么从里面拿啊？必须是recommanded nutrients，否则不行能存新的map。好像是吧RecommendedNutrient移到person里面了已经。可我初始化男女的时候没移啊怎么办啊。怎么理解use的关系。
发现没看图，返回去把图看懂了
好像明白map里存什么了，能写了不？ 不知道两个输入是啥意思。都是产生product。那就可以写了。
发现少写了个box,妈的。是不是要新写啊？
person算是基本完事了吧，不会，呵呵呵呵呵。看看计算。男女应该不用改吧。NP RN也不用改。最下边一行看完了。exception 然后handler。
NB改了参数，还要再改是什么意思啊，难道还不够么。
