See this page of the java API documentation.

Well, you need these import lines:
?
1
2
import java.util.List;
import java.util.ArrayList;
Then, you need to create a List object:
?
1
List<Object> list = new ArrayList<Object>();
Then you can add objects to the list:
?
1
2
3
4
5
6
7
8
Actor actor = new Actor(){}; // some actor to be added to List
list.add(actor);
String text = "abcdefg";
list.add(text);
World world = this;
list.add(world);
int n = 125;
list.add((Integer)n);
The objects added to this list are just random to show different types being added and the type of objects is wide open because I use 'Object' as the type of elements that can be added to the list.
