In Java, a **list** interface is an ordered collection of objects in which duplicate values can be stored. Since a List preserves the insertion order, it allows positional access and insertion of elements. 

List interface is implemented by the following classes: 
* [ArrayList](https://www.educative.io/answers/what-is-an-arraylist-in-java)
* LinkedList 
* Vector 
* Stack 

# Creating list objects
A list is an interface and the instances of a list can be created in the following ways:

* `listType` is the class that is implementing the list interface.
* `objType` is the data type of the values in the list
* `listName` is the name of the list 

// Obj is the type of object to be stored in List.
ListType<objType> listName = new ListType<objType> ();
