List: Unique Common methods: there is a general characteristic is that all can operate the angle mark.
1, adding
void Add (index,element);
void Add (index,collection);
2, delete;
Object Remove (Index):
3, modify:
Object set (index,element);
4, Get:
Object get (index);
int IndexOf (object);
int LastIndexOf (object);
List sublist (from,to);
Note: An iterator that is unique to the 1.List collection. Listiterator is a sub-interface of iterator.
In an iteration, you cannot manipulate the elements in the collection through the methods of the collection object.
Because the concurrentmodificationexception exception occurs.
So, in iterators, you can only manipulate elements with iterators, but the iterator method is limited,
Only the elements can be judged, taken out, removed from the operation,
If you want other operations such as add, modify, and so on, you need to use its sub-interface, Listiterator.
This interface can only be obtained through the Listiterator method of the list collection.
The 2.List set determines whether the element is the same, based on the Equals method of the element.
Second, List interface
