Question

I have a requirement to have a list, where each element must have 2 values.
I want to know what would be the best way to implement it.
Should I use HashSet, HashMap or anything else ?

The list should look like this –

<Elem1_val1, Elem1_val2>, <Elem2_val1, Elem2_val2>, <Elem3_val1, Elem3_val2>, ....
<Elemn_val1, Elemn_val2>,

The important point here is that val1 and val2 belong to same Element.
What would be a good way to implement this?

UPDATE:

1. Can anyone comment about implementing – List<Map.Entry<ClassA, ClassB>>
2. I don’t want to have new class, because I just want to store 2 objects which have
   some co-relation together in one list.

Thanks !

Answer 1

how about creating a class that has two elements and create a List of that class

class DataHelper{
  String element1;
  String element2;
}
