What is the List interface?

• A List is an ordered Collection (sometimes called a sequence). Lists may contain duplicate elements. In addition to the operations inherited from Collection, the List interface includes operations for the following:
  
  Positional access — manipulates elements based on their numerical position in the list. This includes methods such as get, set, add, addAll, and remove.
  Search — searches for a specified object in the list and returns its numerical position. Search methods include indexOf and lastIndexOf.
  Iteration — extends Iterator semantics to take advantage of the list's sequential nature. The listIterator methods provide this behavior.
  Range-view — The sublist method performs arbitrary range operations on the list.
  The Java platform contains two general-purpose List implementations. ArrayList, which is usually the better-performing implementation, and LinkedList which offers better performance under certain circumstances.
