How to create a collection of hashMap
I have a query which returns a collection through ORM.
Now I parse that collection and do so processign based upon a particular value of key null and not null
and I have to create two separate collections out of this main collection.
How do I do that?
Collection will contain Maps.
Collection c1=new HashMap();
c1.add(m1);//m1 is a map containing a pair of keys and vlaues
This above code doesnt work?
Pls help

Why dont you use Vectors or ArrayList ?
List coll1 = new Vector();
coll1.add(obj);
List coll2 = new Vector();
coll2.add(obj);
If you want to use ArrayList just replace new Vector() with new ArrayList();
Both Vector and ArrayList serve the same purpose, except for the difference that Vector is synchronized and ArrayList is not synchronized...
