Java tutorial in Eclipse: how to iterate through a List in Java

The List is the base interface for all list types, and the ArrayList and LinkedList classes are two common List’s implementations.

ArrayList: An implementation that stores elements in a backing array. The array’s size will be automatically expanded if there isn’t enough room when adding new elements into the list. It’s possible to set the default size by specifying an initial capacity when creating a new ArrayList. Basically, an ArrayList offers constant time for the following operations: size, isEmpty, get, set, iterator, and listIterator; amortized constant time for the add operation; and linear time for other operations. Therefore, this implementation can be considered if we want fast, random access of the elements.
