Copy a specified element from one array list to another arraylist

I have two arraylists: A & B. How do I copy a single element of A into B? The elements in question are objects of a custom defined class.

you can loop through the arraylist to find the object and when found use B.add(yourObject);

Small example

Code:

---

MyClass p = a2.get(0);
a1.add(p);

Suppose your element is the first Element in the arraylist a2, get it and add it to your arraylist a1.
