list of maps
Hi,
I have an objects Var {String type, String identifier } and I need to associato it to an Integer; so I used a Map for this.
Then, I must keep many of those Map and so I used this:
Code:
public List< Map<Var,Integer> > mapping = new ArrayList< Map<Var,Integer> >();
1. how declare LinkedHashMap instead just a Map in the right side? The compiler gets an error with that;
2. is it a right thing? It seems to me a very complicated way a 'list of maps'; any alternatives?
thanks.

Re: list of maps
Can you post the error message that the compiler gives you? I am willing to be it is because you have not added the correct import statement for the LinkedHashMap.
As far as 2 goes, if you want a List of Maps, how else would you expect to see it? What seems complicated about this way of doing it? You are indicating that you have a list. In this list the elements will be maps. The maps will contain a Var as a key, and an Integer as the value. Pretty straight forward if you ask me.
