Lists In Java

A Listis 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:

• Positional Access: manipulate elements based on their numerical position in the list.
• Search: search for a specified object in the list and return its numerical position.
• List Iteration: extend Iterator semantics to take advantage of the list's sequential nature.
• Range-view: perform arbitrary range operations on the list.
