Question

I want to put an ArrayList<HashMap<String, Object>> into another ArrayList<HashMap<String, Object>>. How can I do that?

I was trying with the assignment operator (=) but I found out that it just points to the reference, I want to put the elements into another.

Try this:

List<HashMap<String, Object>> newList = new ArrayList<HashMap<String,Object>>();
for (HashMap<String, Object> hm: oldList) {
    newList.add(hm);
}
