Adding objects to a List

I need to add an object to a list, however I do not know how. Can somebody help me?Well, you need these import lines:
Then, you need to create a List object:
Then you can add objects to the list:
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.
import java.util.List; import java.util.ArrayList;
List<Object> list = new ArrayList<Object>();
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);You need to login to post a reply.
