For example, lets say you have two classes:
public class TestA {}
public class TestB extends TestA{}
I have a method that returns a L
You cannot cast List
to List
as Steve Kuo mentions BUT you can dump the contents of List
into List
. Try the following:
List result = new List();
List data = new List();
result.addAll(data);
I've not tried this code so there are probably mistakes but the idea is that it should iterate through the data object adding the elements (TestB objects) into the List. I hope that works for you.
