无法在映射java中插入值 [英] failing in inserting values in maps java
问题描述
我试图在java中插入值到地图上来循环它们并做一些计算，所以我正在做的是读取一个包含如下所示的11k文件的文件夹：

我将这些数据存入地图与关键 Match 然后当我尝试打印地图我得到一个空的！
我试过这个代码其中一个文件，它与我很好。
问题是，当我尝试将它应用于整个文件夹时，我在地图中什么也没有得到。在调试完代码之后，我发现最后一个for循环没有被执行，这个循环是关于存储在map中的循环，但是我无法弄清楚这个循环的原因。我试图将 index ++; 移到for循环之上。代码输入了所提到的for循环，但最后我得到了相同的输出结果
解决方案好吧，你正在进行一个讨厌的覆盖在这里 - 在每次迭代中，你都会丢失所有的值，并且你从0开始计数......
//将它们存储到Maps
for（Match m：Match.values（））{
indexes.put（m，new ArrayList< Integer>（））;
}
另外，在最后一行离开内部循环之后，但是地图会被空的东西覆盖。
将上面的for块移动到创建索引图的部分之后。
I am trying to insert values into maps in java to loop on them and do some calculations so what I am doing is to read a folder of 11k files which containing somethings like these:
ps: all the files have the same structure

I store these data into the map with key Match then when I try to print the map I get an empty one!
I tried this code on one of the files and it worked well with me.
the problem is when I try to apply it on the whole folder I get nothing in the map. After debugging the code I figured out that the last for loop isn't getting executed and this loop is the one concerned with storing in map but I can't figure out the reason behind that. I tried to move index++; to be above the for loops. The code Entered the mentioned for loop but at the end I got the same output
解决方案 Well, you're doing a nasty overwrite here - in each iteration you lose all the values and you start counting from zero...
//storing them into Maps
for (Match m : Match.values()) {
indexes.put(m, new ArrayList<Integer>());
}
Also, after the last line you "break" out of the inner cycle, but the map will be overwritten with empty stuff anyway.
Move the above "for" block right after the part where you create the "indexes" map.
