通过多维数组列表迭代到Java中的hashMap

Question

I have a table as follows

                     Total  Upright  Supine  Meal  PostPr  ChestP     Other
Duration of Period   22:38  14:30   08:08  01:02   06:54   00:48     00:28
Number of Refluxes    5       4       1      0       3       2         0

From this I have created a multidimensional array Arr_ReflDay1_table2d as follows:

 [[Total, Upright, Supine, Meal, PostPr, ChestP, Other], [Duration of Period , 22:38, 14:30, 08:08, 01:02, 06:54, 00:48, 00:28], [Number of Refluxes, 5, 4, 1, 0, 3, 2, 0]]

I want to get it into a HashMap such that the Key is the row and column name a value came from. For example the hashMap might read:

Total_DurationOfPeriod=22:38,Upright_DurationOfPeriod=14:30,Supine_DurationOfPeriod=08:08 etc.

I tried doing this:

Map<String,String> mapReflDay1= new LinkedHashMap<String,String>();
    ArrayList<List<String>> Arr_ReflDay1_table2d = new ArrayList<List<String>>();
        for (int ff=0;ff<Arr_ReflDay1_table2d.size();ff++){
               for (int fg=0;fg<Arr_ReflDay1_table2d.size();fg++){
                  for (int fx=0;fx<Arr_ReflDay1_table2d.get(0).size();fx++){
                            mapReflDay1.put("ReflDay1"+Arr_ReflDay1_table2d.get(0).get(ff)+Arr_ReflDay1_table2d.get(fg).get(0)+","Arr_ReflDay1_table2d.get(ff).get(fx));
        }
                }
                      } 

which gives the key fine but the value seems to only be taken from the final column

Answer 1

Solved it in the end. Just added an extra element to the first inner ArrayList so I was iterating over the same number of elements in each inner ArrayList
