HashMap(key: String, value: ArrayList) returns an Object instead of ArrayList?

Question

I\'m storing data in a HashMap with (key: String, value: ArrayList). The part I\'m having trouble with declares a new ArrayList \"current,\" searches the HashMap for the String

Answer 1

Using generics (as in the above answers) is your best bet here. I've just double checked and:

test.put("test", arraylistone); 
ArrayList current = new ArrayList();
current = (ArrayList) test.get("test");

will work as well, through I wouldn't recommend it as the generics ensure that only the correct data is added, rather than trying to do the handling at retrieval time.
