When primitive data types are automatically converted into it's  wrapper type, it is called boxing. The opposite operation of converting wrapper class objects to it's primitive type is known as unboxing.
ArrayList<Integer> list = new ArrayList<Integer>();
list.add(1); //autoboxing - primitive to object
int number = list.get(0); // unboxing
